Currency Determination No. 2 of 1997

Denomination. The coin is a “$1” coin. Under the Currency Act 1965, a coin of that denomination is legal tender for payment of any amount, subject to any limitations on the number of coins that can be used in a single transaction (the Act itself imposes no limit on $1 coins; the limit for silver coins was historically different but the 1997 determination does not alter that). The denomination fixes the coin’s face value for legal tender purposes, regardless of its metal content. This concept is critical because the coin can be used at par value for debts, but in practice it is unlikely to circulate due to its high silver content.

Standard composition. The coin must be “not less than 99.9% silver”. This is a purity standard. The phrase “not less than” sets a minimum; the coin may be slightly purer but cannot be less pure. This is a common formulation for bullion coins. The composition is a defining feature that differentiates this coin from the standard circulating $1 coin, which is an aluminium‑bronze alloy. The high silver content means the coin is significantly heavier (31.635 g) than the standard $1 coin (about 9 g). This has practical implications: the coin will not fit in standard coin‑counting machines or vending mechanisms designed for the lighter coin. It also means the coin has a melt value that fluctuates with the silver spot price, introducing a speculative element for holders.

Standard weight and allowable variation. The standard weight is 31.635 grams with an allowable variation of ±0.50 grams. This tolerance reflects practical minting limits. Any coin falling outside that range is not a lawful coin under this determination and would be considered defective or counterfeit. The tolerance is relatively generous (about 1.6% of the standard weight), which may account for manufacturing wear and slight variations in composition. For bullion investors, the actual weight may be a concern when calculating silver content; a coin at the lower tolerance (31.135 g) contains slightly less silver than a coin at the upper tolerance (32.135 g). The determination does not require the Mint to guarantee an exact weight, only that the coin meets the specification within tolerance.

Dimensions. Diameter 40.60 mm and thickness 4.00 mm. These are exact measurements. The tolerance applies only to weight, not to dimensions; the instrument does not specify any dimensional tolerance. This is unusual; most coin specifications include a tolerance for diameter and thickness. The absence of an explicit tolerance may imply that the dimensions are nominal and any significant deviation would render the coin non‑conforming. In practice, the Mint’s production would aim for these figures, and minor variations would likely be accepted unless they affect weight. The large diameter (about the size of a typical bullion coin) and moderate thickness give the coin a substantial feel and a surface area suitable for detailed design.

Design codes. The Schedule uses codes S1 (circular), E1 (milled), O1 (obverse with effigy and inscriptions), and R38 (reverse with kookaburra motif and gold cameo). These codes are defined in Part 2. The use of codes is a drafting convenience; the actual visual design is described in words. The obverse is standard for Australian coinage of the era - the Queen’s effigy, country name, and denomination. The reverse is unique to this coin: a kookaburra nesting scene with a gold cameo inset reproducing the design of the Japanese 1871 gold 20 yen coin. The cameo is notable because it is a separate piece of gold set into the silver coin. This introduces a second precious metal (gold) into the coin’s composition, but the determination only specifies the silver composition. The gold cameo is a design feature, not separately specified in terms of purity or weight. This could create ambiguity: is the coin still “not less than 99.9% silver” overall, or does the gold cameo mean the entire coin is not homogeneous? The determination is silent. Likely the composition standard applies to the silver portion, and the gold cameo is a decorative insert that is not part of the “standard composition”. This is a gotcha for anyone trying to assay the coin as a uniform silver piece.

Legal effect. The determination is made under a specific power in the Currency Act. It does not need to be registered on the Federal Register of Legislation at the time (1997 pre‑dates the electronic register) but is a legislative instrument for the purposes of the Acts Interpretation Act. It has the force of law as a delegated legislation. It specifies the coin such that any coin meeting these specs is a lawful coin of the Commonwealth. The determination does not repeal or amend any prior determination; it is additive.

No effect on other determinations. Clause 4 states that this determination does not affect any other determination. This means other coin specifications (for example, for the $5 or $10 silver coins, or for other denominations) remain in force. The Mint may therefore have multiple active determinations for different coins. There is no consolidation or exclusive list; each determination stands on its own.

The Royal Australian Mint. The primary entity affected is the Mint, which must produce the coin in accordance with the specifications. The Mint must source silver of at least 99.9% purity, ensure the weight stays within the allowable variation, control the diameter and thickness to the stated dimensions (including the gold cameo inlay), and strike the coin with the prescribed obverse and reverse designs. The Mint also bears the compliance cost of quality assurance and testing to ensure each coin meets the specs. If the Mint produces coins that fall outside the allowed weight variation or have a different composition, those coins are not authorised by this determination and could be considered unlawful, potentially exposing the Mint to liability under the Currency Act for issuing defective currency. However, the determination does not impose any penalty on the Mint directly; the Currency Act provides for offences relating to counterfeiting and altering coins, but those are aimed at third parties.

Collectors, investors, and bullion dealers. This group is the intended market for the coin. The determination defines the specifications that make the coin a legitimate Australian legal tender silver dollar. Collectors value the coin for its design, limited mintage (likely, though not stated in the instrument), and composition. Bullion dealers buy and sell these coins based on their silver content and numismatic premium. The determination is essential for verifying authenticity: a coin that does not match the weight, dimensions, or design codes is not a genuine mint‑issued coin. Dealers must be able to assay the coin, check weight, measure dimensions, and examine the design to confirm it meets the determination. Failure to do so could result in accepting counterfeit coins, which carries commercial risk. For investors, the coin’s legal tender status may offer advantages in certain tax treatments (e.g., as currency rather than investment gold), but that is external to the determination.

Counterfeiters and those handling counterfeit coins. While not directly affected in a positive sense, the determination indirectly affects criminals by providing the standard against which counterfeiting is judged. Producing a coin that purports to be this $1 silver coin but does not meet the specifications (e.g., lower silver purity, wrong weight, modified design) is likely an offence under sections of the Currency Act dealing with counterfeiting or under the Criminal Code. The determination serves as the authoritative reference for what constitutes a genuine coin. Law enforcement agencies and prosecutors will use it as evidence of the coin’s required specifications.

The general public. In theory, any member of the public could receive this coin as change or use it to pay debts. However, given the high silver content and collector value, it is extremely unlikely to circulate. The determination does not compel anyone to accept the coin. The Currency Act provides that coins are legal tender, but the acceptance of legal tender is not mandatory for private parties in Australia; only government debts must be accepted in legal tender. So the public’s practical interaction with the determination is minimal. They might possess the coin as a collectible and need to know its specs for appraisal or sale.

Other regulators. The Australian Securities and Investments Commission (ASIC) or the Australian Taxation Office (ATO) may have an interest if the coin is sold as an investment product. The determination is relevant for defining the coin’s nature as currency versus a commodity. The ATO’s treatment of gold and silver coins for GST and capital gains tax purposes often hinges on whether the coin meets the definition of “investment gold” under the A New Tax System (Goods and Services Tax) Act 1999. A coin that is 99.9% silver and legal tender likely qualifies as investment gold, but the determination is only one factor; the coin must also meet purity and weight thresholds that the determination satisfies. Thus, the determination indirectly affects tax compliance for sellers and buyers.

No effect on businesses not dealing in coins. The determination imposes no obligations on ordinary businesses, such as retailers, unless they choose to accept the coin as payment. Even then, they bear no duty to verify the coin’s specs; they can accept it at face value without recourse if it turns out to be counterfeit, unless they were negligent. The determination does not create any liability for accepting non‑conforming coins.

Duty of the Royal Australian Mint: ensure compliance with specifications. The Mint has a duty implied by the Currency Act and this determination to produce coins that meet the prescribed specs. While the determination does not explicitly say “the Mint must”, it is a necessary implication: if the Mint issues a coin that does not conform, that coin is not a lawful coin under the determination. The Mint could face administrative consequences, such as being required to recall a defective batch, or reputational damage. The Currency Act does not impose a specific penalty on the Mint for issuing non‑conforming coins, but the Mint’s enabling legislation and general government accountability standards likely impose a duty of care.

Duty of persons dealing with the coin: no express duties. No person other than the Mint is given a duty under this instrument. Private parties have no obligation to check the specifications before accepting or using the coin. However, persons who knowingly possess or utter counterfeit coins that purport to be this coin commit an offence under the Currency Act (sections 15 to 18). The determination is relevant to proving that a coin is counterfeit: if it does not match the weight, composition, or design, it is not a genuine coin. So while the determination itself does not create a duty, it informs the application of criminal laws.

Rights of holders of the coin. Holders of a genuine coin have the right to use it as legal tender for the payment of any debt denominated in Australian dollars, up to its face value of $1. However, creditors are not obliged to accept more than a certain number of coins? The Currency Act s 16 provides that a tender of payment of a debt is valid if made in Australian currency, but it is subject to any limits on coin denominations. For coins of denominations of $1 or more, there is no limit on the number that may be used; only coins of smaller denominations are limited (e.g., 50c coins limited to $5, etc.). So a holder could in theory pay a $10,000 debt with 10,000 of these silver dollars, but that would be impractical and the creditor could refuse unless the debt is a government debt. In practice, the right is theoretical. Holders also have the right to sell the coin on the secondary market for its numismatic or melt value, and the determination assures buyers of its provenance.

Right to verification. Any person inspecting a coin claimed to be this determination has a right (through this instrument) to know the exact specifications against which to verify it. The determination is a public document, accessible via the Federal Register of Legislation. This transparency is a benefit to consumers: they can check the stated weight, dimensions, and design details to detect counterfeits. However, the determination does not provide a certification service; the Mint does not issue certificates for each coin. The right is merely informational.

No private right of action. The determination does not create a private right to sue for breach. If a person buys a coin that turns out not to meet the specs, their remedy lies in contract law or consumer law (Australian Consumer Law) rather than under this instrument. The determination is relevant as evidence of the coin’s intended specifications, but it does not itself impose a duty on the seller to ensure the coin meets those specs. The seller could be liable for misrepresentation if they claim the coin is genuine when it is not, but the determination is not the source of that duty.

Effect on contractual obligations. If a contract explicitly refers to “1997 silver kookaburra dollar as specified in Currency Determination No. 2 of 1997”, then the determination’s specifications become terms of the contract. Non‑conforming coins would constitute a breach. This is a right created by the contract, not by the instrument.

Rights of the Commonwealth. The Commonwealth (through the Mint) retains the right to specify and issue this coin. The determination does not grant any rights to others to produce the coin. Unauthorised reproduction would infringe the Commonwealth’s rights in the coin design and possibly trade dress, but those are matters of intellectual property law, not this instrument.

No duty on the Mint to continue issuing. The determination does not oblige the Mint to mint or issue any particular number of coins. It merely sets the specs for any coin of that denomination. The Mint can decide to produce none, some, or many. This is a right, not a duty.

The instrument itself contains no penalty provisions. Penalties for non‑compliance with the specifications arise under the Currency Act 1965 and other legislation. The most relevant are the offences of counterfeiting and altering coins. Under section 15 of the Currency Act, a person who forges or counterfeits any coin that is current in Australia is guilty of an indictable offence. The penalty is imprisonment for up to 10 years (as set out in the Act). A coin that purports to be this silver dollar but does not meet the specifications (e.g., less silver, wrong weight) is a counterfeit. Similarly, section 16 makes it an offence to alter a genuine coin (e.g., by clipping, filing, or adding material) so as to diminish its weight or change its appearance. The determination’s weight tolerance is critical here: a coin that has been altered to fall below the lower tolerance of 31.135 g would be an altered coin. Section 17 prohibits knowingly uttering or possessing counterfeit or altered coins with intent to utter. The penalties for these offences include imprisonment and fines.

The determination serves as the definition of the genuine coin. In a prosecution, the Crown would need to prove that the coin in question does not match the specifications in the determination. For example, a chemical assay could show silver content below 99.9%, or precise weighing could show weight outside the allowable variation. The absence of a dimensional tolerance in the determination could make it harder to prove alteration of diameter or thickness; but any visible change from the nominal 40.60 mm or 4.00 mm could support an inference of alteration. However, the lack of a stated tolerance for dimensions might allow a defence argument that minor wear or manufacturing variations are not alterations, as long as weight remains within tolerance.

Enforcement is carried out by the Australian Federal Police and other law enforcement agencies. The Australian Transaction Reports and Analysis Centre (AUSTRAC) may also be involved if the coin is used in money laundering, given its high value. The determination itself does not create any enforcement powers; it is a standard of proof.

Civil enforcement is unlikely. There is no regulator specifically responsible for ensuring that the Mint complies with the determination. The Mint is an agency within the Commonwealth, and any non‑compliance would be an internal government matter rather than subject to civil penalty. If a person suffers loss from receiving a non‑conforming coin (e.g., a collector pays a premium for a coin later found to be defective), they may sue the seller for breach of contract or under Australian Consumer Law, but not under this determination.

The determination does not create any infringement notice regime, nor does it delegate power to issue fines. It is purely technical. However, the existence of the determination means that the Mint can be held accountable through parliamentary processes or through the Auditor‑General if it fails to produce coins meeting the specs, but those are political and administrative remedies, not legal penalties.

For bullion dealers, the risk is commercial: if they unknowingly sell counterfeit coins that do not match the determination, they could face liability to buyers and reputational harm. They may also be exposed to charges if they intentionally sell counterfeits. The determination is a tool for due diligence: dealers should compare any coin against the specs. Failure to do so could be seen as negligent if the coin is obviously non‑conforming.

Overall, the penalty landscape is driven by the Currency Act, not this instrument. The determination’s value is as a reference document for law enforcement and the courts. Without it, proving what constitutes the genuine coin would be difficult.

Currency Act 1965. This determination is made directly under subsection 13A(1) of the Currency Act. That section empowers the Treasurer (or delegate) to determine specifications of coins. The determination must be read in conjunction with the rest of the Currency Act, particularly sections dealing with legal tender (s 16), offences (ss 15‑18), and the power to mint coins (s 13). The Currency Act sets the framework: only coins that meet a valid determination are lawful. The determination fills in the specifics for this coin. Any inconsistency with the Act would be resolved in favour of the Act, but none appears.

Criminal Code 1995. Offences of counterfeiting currency are also covered by the Criminal Code, specifically Part 3.5 (False documents and currency). The Code overlaps with the Currency Act offences; in practice, prosecutions may proceed under either. The determination is still used as evidence of the genuine coin’s specs. The Code provides for higher penalties for counterfeiting of “current” coins, and this coin is current (it is legal tender). The determination confirms its status.

Competition and Consumer Act 2010 (Australian Consumer Law). A seller of this coin must not engage in misleading or deceptive conduct about its specifications. Claiming a coin is the “1997 silver kookaburra dollar” when it does not match the determination is likely misleading. The determination provides an objective benchmark. Consumers who buy a non‑conforming coin can seek remedies such as refund or damages. The ACL does not directly reference the determination, but the court would look to the determination to determine if a representation was false.

A New Tax System (Goods and Services Tax) Act 1999. The GST treatment of gold and silver coins often depends on whether the coin is of investment grade. For silver, the shorthand is often that a coin with at least 99.9% purity and legal tender status qualifies for GST‑free treatment as investment gold or silver (under the precious metals provisions). This determination proves that the coin meets the purity requirement. However, the determination alone is not enough; the coin must also be of a kind specified by regulation under the GST Act. Practitioners should check current ATO rulings.

Income Tax Assessment Act 1997. Capital gains tax treatment of coins is complex. A coin that is legal tender may be treated as a personal use asset if held for personal use, but bullion coins held as investments may have different treatment. The determination is relevant to establishing the coin’s nature as investment silver. The absence of explicit guidance in the determination means reliance on general tax rules.

Coins and Other Currency Regulations. There may be regulations under the Currency Act that prescribe additional rules for coin specifications, such as tolerances for diameter. The determination does not incorporate any such regulations; it stands alone. But any regulation made after 1997 that conflicts with the determination would override it, unless the determination is saved by a transitional provision. No such conflict is known.

Other determinations. Clause 4 of this determination says it does not affect any other determination. This means that the Mint may have multiple active determinations for different coins. For example, a later determination could specify a 1‑ounce silver coin with a different design. If that later determination also covers a $1 silver coin, there could be two different $1 silver coins simultaneously. The holder must check which determination applies to a particular coin based on its year and design. The 1997 determination is specifically for the 1997‑dated coin with the kookaburra and Japanese coin cameo. Later years might have separate determinations. This instrument is not a consolidated document.

State and territory laws. State laws on precious metal dealers and pawnbrokers may require identification of persons selling bullion coins. The determination does not interact directly with those laws, but the coin’s status as legal tender may exempt it from certain reporting requirements (e.g., in some states, legal tender coins are not subject to the same rules as bullion bars). Practitioners must check local legislation.

Intellectual property laws. The coin design includes an effigy of the Queen, which is subject to crown copyright, and the kookaburra artwork likely owned by the Mint. The gold cameo reproduction of the Japanese coin may raise copyright issues, but those are not addressed in the determination. The determination does not grant any intellectual property rights; it merely describes the design. Unauthorised reproduction of the design for counterfeit purposes would infringe copyright and possibly trade mark rights under the Trade Marks Act 1995 (e.g., if “AUSTRALIAN KOOKABURRA” is a registered mark).

Money laundering and counter‑terrorism financing laws. Under the Anti‑Money Laundering and Counter‑Terrorism Financing Act 2006, bullion dealers and persons dealing in precious metals may have obligations. The coin’s high silver value means it could be used as a value transfer mechanism. The determination helps identify the coin as a specific product, but does not create or remove AML/CTF obligations.

Currency Determination No. 2 of 1997 has no recorded amendment history within the instrument itself. The instrument as provided does not contain any amendment clauses, and there is no reference to previous amendments. It is a single‑subject determination that specifies one coin. Under the Legislation Act 2003, legislative instruments are kept on the Federal Register of Legislation, and any amendments would be noted there. A check of the register (if available) would reveal whether this determination has been amended. For the purpose of this deep dive, based solely on the source, there is no amendment history. The instrument was made on 18 April 1997, signed by the Assistant Treasurer, and commenced on 21 April 1997. It has not been repealed by any later instrument of which we are aware from the text. It may have been superseded by a later determination for the same denomination and year, but that is not evident. The absence of amendment history is significant: it means the coin’s specifications have remained unchanged for over 25 years. However, the Mint may have stopped minting this coin in 1997, and later years might have similar but not identical coins (e.g., the 1998 silver kookaburra dollar would be covered by a separate determination). The determination is a snapshot of one coin issue. There is no expiry date. The determination remains in force unless expressly revoked or unless the Currency Act is amended to terminate all existing determinations. It is possible that the determination has been implicitly revoked by a later determination covering the same specifications, but clause 4 suggests each determination is independent. In practice, the Treasury may periodically make new determinations for each year’s coin, and the 1997 determination would remain on the books but be effectively obsolete for new minting. For legal purposes, it still defines the genuine 1997 coin.

There is no mention of litigation within the instrument itself. Since this is a ministerial determination of coin specifications, litigation is unlikely to be reported in the instrument. I am not aware of any reported Australian cases that have involved this specific determination. It is plausible that the determination has been cited as evidence in a counterfeiting prosecution, but such cases are rarely reported in detail. The determination’s technical nature means it would only become a subject of litigation if there were a dispute about whether a particular coin met the specs, or if someone challenged the validity of the determination (e.g., on the ground that the Treasurer exceeded power under s 13A). No such challenge is apparent. The determination is a routine exercise of a delegated power; litigation would be unusual. If a case did arise, the court would likely give considerable deference to the Mint’s manufacturing tolerances and the Minister’s discretion. The determination itself is not reviewable on the merits; it is a legislative instrument that can be challenged on administrative law grounds if it is ultra vires or procedurally flawed, but none of those issues arise from the text. The instrument was made by the Assistant Treasurer acting for the Treasurer, which is a proper delegation under the Acts Interpretation Act. The citation clause is proper. The determination was gazetted or published as required at the time.

For practitioners searching for case law, terms like “Currency Determination No. 2 of 1997” might not yield results. Instead, cases involving counterfeiting of the 1997 silver kookaburra dollar would refer to the coin by description. The determination would be tendered as a document. The absence of published litigation is not surprising. Bullion coin cases often settle, and prosecutions for small‑scale counterfeiting may not go on appeal. Thus, the litigation history is effectively nil based on the source.

Weight tolerance applies only to weight, not dimensions. The determination specifies a standard weight with a ±0.50 gram variation, but does not give any tolerance for the diameter (40.60 mm) or thickness (4.00 mm). This creates a potential ambiguity. If a coin’s diameter is 40.55 mm, is it non‑conforming? Strictly, the determination says the dimension is 40.60 mm, but without a stated tolerance, the law might imply a reasonable tolerance or treat the dimension as nominal. This could be exploited: counterfeiters could argue that a slight variation in diameter is permissible because the determination is silent, while prosecutors would argue that “40.60 mm” is an exact requirement. In practice, the Mint would have internal manufacturing tolerances, but those are not stated here. Anyone verifying a coin should accept that minor wear or normal striking variations do not alter the coin’s legal status, but a significant deviation in diameter could indicate a counterfeit.

Gold cameo not covered by composition specification. The standard composition is “not less than 99.9% silver”. But the coin includes a gold cameo. The overall composition of the entire coin is not 99.9% silver because it contains gold. The determination does not specify the purity or weight of the gold cameo. This means that a chemical assay of the whole coin would yield a lower silver percentage than 99.9%. A person expecting the entire coin to be 99.9% silver would be misled. The determination likely intends that the silver portion is 99.9%, but it does not say that. This is a trap for purchasers who rely on the composition spec without examining the design. Assayers should test the silver area only, not the cameo.

No specification of the gold cameo’s composition or weight. The determination is silent on the gold’s fineness, weight, or size. This leaves room for variation. The Mint could in theory use different gold alloys for different mint runs, and the coin would still meet the determination as long as the silver portion is compliant. Investors buying for gold content would have no guarantee. The coin’s value is primarily as a silver coin with a gold cameo accent; the cameo is purely aesthetic. There is no regulatory assurance for the gold.

Coin is not the standard circulating dollar. Many people assume the $1 coin is the small, gold‑coloured aluminium‑bronze coin. This silver coin is much larger and heavier. It does not fit in a standard wallet or coin machine. Anyone receiving it in change (extremely unlikely) would be surprised. The determination does not warn of this. Retailers who accept it at face value without checking could lose money if they later discover it is a collectible worth more than $1. Conversely, a retailer could sell the coin as bullion for a premium.

Absence of a mint mark or serial number. The determination does not require any unique identifier. This makes it easier for counterfeiters to produce convincing fakes because there is no expectation of a serial number. Anti‑counterfeiting features are not specified. The only security is the intricate design and the gold cameo, which is difficult to replicate.

Legal tender status does not guarantee acceptance. Despite being legal tender, no private business is required to accept it. This is a general legal principle often misunderstood. The determination reinforces the technical status, but it does not compel use.

Outdated denomination. The coin is $1, yet its silver content alone was worth much more than $1 even in 1997 (silver was about $5 per ounce then; the coin has 1 oz silver). Now silver is around $25 per ounce. The coin is essentially a bullion piece masquerading as a dollar. People using it as $1 would be giving away significant value. The determination does not note this.

Possible confusion with later years. The Mint has issued silver kookaburra coins in many years. Each has its own determination. The 1997 coin is the first year of issue (the R38 design is specific). Holders should not assume that later year coins have the same specs; they may differ (e.g., later years might have different reverse designs, different standards of silver, or no gold cameo). The 1997 determination is unique.

No obligation to inform the public. The determination is a legislative instrument but is not widely known. Many holders of the coin may not be aware of the exact weight tolerance or composition standard. This can cause disputes in private sales. A buyer may claim a coin is underweight and therefore counterfeit, but if it is within the tolerance it is genuine. Sellers should be prepared to produce a copy of the determination.

No remedy for non‑conforming Mint‑issued coins. If the Mint accidentally issues a coin that falls outside the tolerance, that coin is technically not a lawful coin under this determination. However, the Mint is unlikely to recall it. Holders of such a coin might have a defective product but no clear legal recourse against the Mint. The coin’s value as a collectible might be diminished.

The primary entity that must comply with the determination is the Royal Australian Mint during the minting process. For private individuals and businesses, compliance is generally indirect: they must ensure that when they deal with the coin as being a genuine legal tender coin, they do not commit an offence by altering or counterfeiting it. There are no proactive compliance steps for most people.

For the Royal Australian Mint. The Mint must establish quality control procedures to ensure that every coin produced under this determination meets the specifications. This includes: sourcing silver of at least 99.9% purity (verified by assay); striking the coin to the correct weight within the tolerance of 31.635 g ± 0.50 g (so actual weight must be between 31.135 g and 32.135 g); controlling the die to produce a diameter of 40.60 mm and thickness of 4.00 mm (even though no tolerance is given, the Mint should target these exactly and reject coins with visible deviation); ensuring the gold cameo is properly inserted and does not materially affect the coin’s weight (the cameo weight is not specified, so the Mint must ensure the silver portion alone meets purity - probably the cameo is added after the blank is struck, or the blank includes a recess). The Mint must also maintain records of production runs and testing. Any batch that fails quality checks should not be issued. The Mint should also keep the determination accessible to staff involved in production.

For bullion dealers and collectors. Compliance is about due diligence to avoid handling counterfeit coins. Dealers should have a procedure for verifying coins tendered as 1997 silver kookaburra dollars. This includes weighing the coin on a calibrated scale that reads to at least 0.01 g. If the weight is outside 31.135 g to 32.135 g, the coin is likely counterfeit or altered. Conduct a visual inspection: check the diameter with callipers (40.60 mm) - due to wear, a slight reduction may be acceptable but should be consistent with use. Examine the design details: the obverse should have the inscriptions exactly as described; the reverse should show the kookaburra and the gold cameo. The cameo should be gold coloured and inset. A step further: perform a specific gravity test or XRF analysis to confirm silver purity of at least 99.9% on the silver surface area (avoid the cameo). Documentation: maintain a record of verification per coin and a copy of the determination on hand.

For law enforcement and prosecutors. When preparing a case involving an alleged counterfeit of this coin, obtain a certified copy of Currency Determination No. 2 of 1997 from the Federal Register of Legislation. Arrange for an expert to test the coin against the specs: weight, composition (e.g., scanning electron microscopy or chemical assay), dimensions, and design comparison with a genuine sample. The determination should be tendered as evidence of the standard. The prosecution must prove that the coin does not match. The absence of a dimensional tolerance may require expert testimony on what constitutes a genuine coin.

For ordinary holders. No compliance is required. However, if the holder intends to sell the coin, they should be prepared to demonstrate its authenticity. They can weigh it and compare to the determination. They may also seek certification from a grading service (e.g., PCGS or NGC) which will verify the coin against the mint’s specs. That certification serves as third‑party compliance.

For financial institutions. If a bank or bullion exchange accepts the coin as a deposit or in trade, they should have a policy for identifying the 1997 silver dollar. This may include training staff to recognise the coin and using verification tools. They may also need to report cash‑equivalent transactions under AML/CTF rules. The determination helps define the asset.

For tax advisors. When advising clients on the tax treatment of the coin, obtain a copy of the determination to confirm purity and weight. This helps in applying the GST‑free treatment for investment‑grade precious metals and establishing cost base for CGT purposes. Keep the determination in the client’s tax file as supporting evidence.

General best practice. Anyone materially dealing with the coin should download and retain a copy of the determination from the Federal Register of Legislation. The instrument is short and can be printed. It should be consulted whenever there is doubt about a coin’s authenticity or specifications. Given that the coin is nearly 30 years old, wear and tear may cause slight weight loss; however, significant weight loss below 31.135 g would render the coin non‑conforming. Sellers should disclose any weight loss honestly. Buyers should verify. The determination is the definitive benchmark.
