Currency (Royal Australian Mint) Determination 2006 (No. 3)

The central concept is specification of coinage under statutory authority. Subsection 13A(1) of the Currency Act 1965 empowers the Treasurer (or a delegate such as a Parliamentary Secretary) to determine, by legislative instrument, the denomination, standard composition, standard weight and allowable variation, dimensions, and design of a coin. This determination exercises that power for 15 specific coins. The concept of standard composition matters for several reasons. For precious metal coins, the specification of at least 99.9 per cent silver or at least 99.9 per cent gold (and for the $10 coin, at least 99.99 per cent gold) establishes a minimum fineness. The Mint may use higher purity but not lower. For base metal coins, the composition is given as copper, aluminium and nickel without specifying exact proportions, which leaves some manufacturing flexibility within that ternary alloy description. The concept of allowable variation from standard weight is critical. The instrument does not merely state a single weight; it states a standard weight and a tolerance. For example, the silver $5 coins have a standard weight of 36.31 grams plus or minus 0.54 grams, meaning a coin weighing between 35.77 grams and 36.85 grams is within specification. A coin outside that range may not be an authorised coin, even if it is otherwise identical. This matters for legal tender status and for potential fraud or defective minting claims. The concept of design is also specified in detail. Every coin bears an obverse effigy of Queen Elizabeth II with the initials IRB (Ian Rank-Broadley, the designer), surrounded by the inscriptions ELIZABETH II and AUSTRALIA followed by the year (2006 or 2007 depending on the item). The reverse designs are commemorative, depicting specific artworks, historical events, or cultural references. These include Grace Cossington Smith's Curve of the Bridge, William Dobell's Margaret Olley, Margaret Preston's Implement Blue, Clifford Possum Tjapaltjarri's Yuelamu Honey Ant Dreaming, characters from Norman Lindsay's The Magic Pudding, surf lifesavers, the Sydney Harbour Bridge (marking the 75th anniversary of its opening in 1932), and the Ashes trophy (marking the 125th anniversary of the 1882 Test). The edge description also matters: some coins have continuously milled edges, others have 14 segments of which 7 are milled and 7 are plain. This is a security feature and a design element that must be reproduced exactly. The concept of shape is uniformly circular across all items, but that is itself a specification that could theoretically differ for other coins under different determinations.

The direct effect falls on the Royal Australian Mint, which must mint coins to these exact specifications or risk producing coins that are not authorised under the Currency Act. The Mint's production line, quality control, and inventory management must accommodate the specific weight tolerances, dimensions, edge types, and design details for each of the 15 items. This includes sourcing silver of at least 99.9 per cent purity or gold of at least 99.99 per cent purity for the $10 coin, and ensuring that base metal $1 coins are within 0.280 grams of 9.00 grams. Secondary effects fall on coin dealers, bullion traders, and collectors. Precious metal coins specified under this determination carry a face value that is far below their metal content: a silver $5 coin with 36.31 grams of 99.9 per cent silver has a silver value well above $5 at any plausible silver price, and the gold $10 coin at 3.133 grams of 99.99 per cent gold is worth many times $10. These coins are not intended for circulation. They are collector and investment products. Dealers who buy and sell them must know the specifications to verify authenticity and to price them correctly. The market for these coins depends on the integrity of the specification as an assurance of weight and purity. Any deviation from the specification, whether by the Mint or by a counterfeiter, affects the secondary market. Collectors who acquire these coins acquire an asset whose legal status as Australian legal tender depends on compliance with the specification. A coin that is underweight outside the allowable variation may not be legal tender and may have reduced collectable value. Investors who treat these coins as stores of value, particularly the gold and silver pieces, rely on the specification as a guarantee of metal content. The Reserve Bank of Australia is indirectly affected because these coins are legal tender, though in practice they will rarely if ever be presented for payment. The general public is affected only insofar as someone might receive one of these coins in a transaction and need to know its legal standing. The Sydney Harbour Bridge and Ashes themed coins may have broader cultural resonance, but the legal effects are narrow. The determination also affects the Commonwealth itself, which bears the cost of minting precious metal coins whose face value is below the cost of materials, production, and distribution. The difference is effectively a subsidy to collectors and investors, paid for by the Mint's budget. The private sector entities that design, market, and distribute these coins also have an interest in the specifications being precise and stable, because their marketing materials and inventory descriptions rely on them.

The primary duty created by this determination falls on the Royal Australian Mint: it must strike each coin exactly as specified in Schedule 1. This is not merely an internal quality standard. Because the determination is a legislative instrument made under the Currency Act, a coin that does not meet the specifications may not be an authorised coin. The Mint therefore has a legal duty to maintain production within the allowable weight variation, to use the correct composition, and to reproduce the designs exactly as described. There is a corresponding duty on the Mint not to issue coins that deviate from the specifications. The Treasurer or their delegate has the right to determine specifications under subsection 13A(1), but once a determination is made and registered, the specifications are fixed until amended or repealed by a later instrument. The public has the right to treat coins minted to these specifications as legal tender under the Currency Act, subject to the limits set out in that Act for payments involving large quantities of coins. For a $5 silver coin, it would be legal tender for debts up to that amount. However, because the metal content is worth many times the face value, no rational person would use it to discharge a $5 debt. The right to legal tender status is therefore largely theoretical for these coins. Holders of these coins have the right to redeem them at face value with the Reserve Bank of Australia under the Currency Act, but doing so would mean surrendering a coin worth substantially more than its face value in metal content, which no informed person would do. The practical right is the right to own, hold, sell, and transfer the coin as a piece of property. The specification gives the holder a legal benchmark for verifying authenticity and quality. If a holder suspects a coin is counterfeit or defective, the specification provides the standard against which the coin can be tested. Dealers have a duty not to misrepresent the specifications when selling these coins. Australian Consumer Law applies separately to any false or misleading representations about the composition, weight, or purity of a coin. The determination does not itself impose consumer law duties, but it provides the objective standard against which such representations can be measured. Collectors have no duty under this instrument, but they bear the risk of relying on the specification as a guarantee of future value. The Mint has no duty to buy back coins at a premium above face value, and the secondary market price fluctuates with precious metal prices and collector demand independently of the specification.

This determination does not itself create penalties. It is a specification instrument, not a penal statute. The enforcement consequences arise from the Currency Act 1965 and other Commonwealth laws that refer to the specifications of coins. Section 15 of the Currency Act makes it an offence to deface, mutilate, or break up a coin that is current and legal tender. The specifications in this determination define what qualifies as a current coin for those provisions. If a person defaces a silver $5 coin minted to these specifications, they commit an offence under section 15, with a penalty of up to 10 penalty units at the time of the Act. The more serious enforcement threat is for counterfeiting. The Criminal Code Act 1995 contains offences for counterfeiting coins, which include making a coin that resembles an authorised coin. The specification provides the authoritative benchmark for determining whether an object is a counterfeit. A fake silver $5 coin that purports to be 99.9 per cent silver but is actually base metal with a silver plating, or that has the wrong weight, falls outside the specification and may be counterfeit. The determination does not create a private right of action. A collector who buys a coin that does not meet the specification cannot sue under this instrument. Their remedy lies in contract law for breach of description, or in Australian Consumer Law for misleading conduct or breach of a guarantee as to description or quality. The specification is relevant evidence in such a proceeding because it establishes what the coin should have been. The Mint faces no direct penalty under this determination for producing coins that deviate from the specifications. However, if the Mint knowingly issued non-conforming coins, it could face administrative consequences, reputational damage, and possibly liability under the Public Governance, Performance and Accountability Act 2013 for failing to use Commonwealth resources properly. The weight tolerances are wide enough that minor production deviations are unlikely to cause problems. A variance of 0.54 grams on a 36.31 gram coin is about 1.5 per cent, which allows reasonable manufacturing tolerance. The enforcement reality is that these are collector coins sold at a premium. The market polices authenticity through independent grading and verification services. A dealer who sells a coin that does not meet the specification faces commercial rather than criminal consequences, unless the deviation amounts to fraud. The specifications therefore function primarily as a commercial standard rather than a law enforcement tool, though criminal counterfeiting remains a real risk for valuable precious metal coins.

The determination sits under the Currency Act 1965, which is the parent statute. Section 13A of that Act is the enabling provision, and this determination is one of many that have been made under it over time. The relationship with other determinations is addressed by clause 4: the specifications in this Schedule do not affect any other determination of the specifications of a coin. That means multiple coins of the same denomination can coexist under different determinations. For example, there may be other $1 coins specified under earlier or later determinations that remain current alongside the items in this Schedule. Each coin is authorised independently. The interaction with the Criminal Code is indirect but important. Division 143 of the Criminal Code deals with counterfeiting currency, including coins. The definitions in that Division refer to an authorised coin, which means a coin that is issued as legal tender under a law of the Commonwealth. The specification in this determination is conclusive evidence of what constitutes an authorised $5 silver coin with the Grace Cossington Smith design, for example. A counterfeit that reproduces that design but fails to meet the weight, composition, or dimensional standards is a counterfeit of an authorised coin. The determination also interacts with the Reserve Bank Act 1959 and the Currency Act provisions on legal tender. Section 16 of the Currency Act provides that a coin that is made and issued under the Act is legal tender. The determination specifies the coins that the Mint is authorised to produce, so it defines which coins qualify for legal tender status. However, the Currency Act imposes limits. For silver coins above 20 cents, payments are limited to $5 face value per transaction. For gold coins, the limit is higher. These coins, being $1, $5, $10, or 20 cent denominations, would be legal tender within those limits. The interaction with the Competition and Consumer Act 2010 (Australian Consumer Law) arises because the sale of these coins by dealers involves goods with a description. Section 29 of the ACL prohibits false or misleading representations about the quality, purity, or composition of goods. The specification provides the objective standard against which a dealer's description is measured. If a dealer describes a coin as 99.9 per cent silver when it is not, the specification is the benchmark for proving the misrepresentation. There may also be interaction with precious metals marking laws at the state and territory level, though those typically apply to bullion bars rather than legal tender coins. Because these coins are legal tender, they may be exempt from some marking requirements that apply to private bullion products. The determination has no interaction with tax law directly, but the classification of these coins as legal tender or as collector items affects their treatment for capital gains tax and goods and services tax. A $5 silver coin held as an investment may be treated as a personal use asset or as a collectable, with different CGT consequences, depending on the taxpayer's purpose in acquiring it.

This instrument is the Currency (Royal Australian Mint) Determination 2006 (No. 3). The title indicates it is the third such determination made in the 2006 calendar year. There were at least two earlier determinations in 2006, though their contents are not stated in this instrument. The existence of earlier determinations confirms that the Mint produces multiple batches of specified coins each year, each requiring a separate legislative instrument to authorise them. The determination was made on 30 October 2006 by Chris Pearce as Parliamentary Secretary to the Treasurer. It commences on the day after registration on the Federal Register of Legislation. Registration and commencement are standard for legislative instruments under the Legislation Act 2003. The instrument has not been amended subsequently; it stands as originally made. However, the specifications in Schedule 1 contain one minor internal oddity. Item 12 specifies Australian 2006 on the obverse, while all other items specify Australian 2007. Item 12 is a cupro-nickel $1 coin commemorating the Sydney Harbour Bridge 75th anniversary, and it carries the year 2006 despite the commemorative event being 1932 to 2007. This may reflect the year of minting or a deliberate design choice. The instrument does not explain the discrepancy. The obverse design for Item 4 (Clifford Possum Tjapaltjarri $5 coin) and Items 14 and 15 (Ashes coins) includes the inscription FIVE DOLLARS or 10 DOLLARS on the obverse in addition to the reverse, which is a variation from the other coins where denomination appears only on the reverse. This is a design detail specified in the instrument. The instrument was registered and published as a legislative instrument, making it publicly accessible and judicially noticeable. It would have been tabled in Parliament under the Legislation Act 2003 and subject to disallowance, though no disallowance occurred. The determination remains in force unless expressly repealed or superseded by a later determination. Because clause 4 preserves the effect of other determinations, the coins specified here remain authorised even if later determinations specify additional coins of the same denominations. The practical lifespan of these specifications is tied to the Mint's production run for each coin. Once the Mint stops producing a particular design, the specification remains on the register but becomes dormant. There is no mechanism in the instrument for automatic repeal after production ceases.

The instrument cannot be expected to generate much litigation. It is an administrative specification of physical attributes. The source text itself discloses no cases. There is no reported case in which this particular determination has been the subject of judicial consideration, and it is highly unlikely that any exists. The legal questions that could arise would involve disputes about whether a particular coin meets the specification, or whether a coin that does not meet the specification can still be legal tender. A hypothetical case could involve a collector who purchases a coin represented as being minted to these specifications, only to discover the weight is outside the allowable variation. The collector might sue the dealer for breach of contract or misleading conduct. In such a case, the determination would be admissible as evidence of the required specifications. The court would compare the actual coin against the Schedule. Because the allowable variations are expressed as tolerances, the court would apply them mechanically. A more complex case could involve a dispute between the Mint and a contractor about whether coins supplied met the specification. If the Mint outsourced minting or blank production, a contractor who delivered blanks outside the weight tolerance could be in breach of contract. The specification would define the contractual standard. Criminal prosecutions for counterfeiting would be the most serious litigation context. A counterfeiter charged under the Criminal Code would have the determination introduced as evidence that the genuine coin exists and has those specifications. The trier of fact would compare the alleged counterfeit to the specification. Cases could also arise about whether a particular coin is an authorised coin for the purpose of legal tender. For example, if a person attempted to use a silver $5 coin to pay a debt and the creditor refused on the basis that the coin was not legal tender, the debtor might need to establish that the coin conforms to the specification. In practice, no one would use a silver bullion coin worth thirty dollars of silver content to pay a five dollar debt, so this scenario is abstract. The only other realistic litigation category is tax disputes. If the Commissioner of Taxation treated a silver $5 coin as not being legal tender for the purposes of a tax provision that distinguishes between currency and collectables, the specification would be relevant. The ATO would likely accept that coins minted to these specifications are legal tender regardless of their market value. The absence of litigation is itself informative: it suggests the specifications are unambiguous and the Mint produces coins that conform within the tolerances. The instrument is designed to be administrative and routine, not a battlefield for legal contestation.

There are several traps for the unwary in this instrument. First, the allowable weight variation is not symmetric. The instrument states standard weight and allowable variation using a plus-minus symbol: for the silver $5 coins it is 36.31g plus or minus 0.54g. This means the minimum permissible weight is 35.77 grams and the maximum is 36.85 grams. A coin that falls outside that range, even by a fraction of a gram, does not meet the specification and may not be an authorised coin. A collector who weighs a coin and finds it at 35.70 grams should be concerned. The tolerance on the base metal $1 coin is plus or minus 0.280 grams on 9.00 grams, which is a tighter relative tolerance of about 3.1 per cent. The gold $10 coin has the tightest relative tolerance at plus or minus 0.09 grams on 3.133 grams, which is about 2.9 per cent. Second, the design descriptions are prescriptive and contain small details that could be missed by someone verifying authenticity. The obverse of many coins does not include the denomination, but Items 4, 14, and 15 do include denomination on the obverse. That means a $5 silver coin with the Ashes design should have FIVE DOLLARS on both sides, while a $5 silver coin with the Grace Cossington Smith design has the denomination only on the reverse. A coin that is otherwise identical but omits the obverse denomination inscription for Item 14 would not match the specification. Third, the edge type varies. Items 1 through 4 (silver $5), Items 8 and 9 (20 cent), Items 10, 14, and 15 (silver $5 and gold $10) have continuously milled edges. Items 5 through 7, 11, 12, and 13 ($1 coins) have 14 segments with alternating milled and plain sections. A dealer or collector who assumes all $1 coins have the same edge type could be misled. Fourth, Item 12 specifies a 2006 obverse year while the commemorative theme is 1932 to 2007. This is a deliberate design choice, but someone expecting the obverse to say 2007 might wrongly reject a genuine coin as non-conforming. Fifth, the items are not numbered in denomination order. Items 1 through 4 are $5, Item 5 is $1, Item 6 is $1, Item 7 is $1, Items 8 and 9 are 20c, Items 10 and 14 are $5, Items 11 through 13 are $1, and Item 15 is $10. Someone scanning the Schedule could easily miss an item by assuming a tidy numerical ordering. Sixth, the composition of the base metal $1 coin is stated only as copper, aluminium and nickel, without proportions. This means there is no single chemical fingerprint for those coins; any alloy of those three metals in any proportion could theoretically satisfy the specification as long as it is within the weight tolerance. This creates a possible ambiguity if someone tries to verify composition, though in practice the Mint uses a standard alloy. Seventh, the obverse design for all coins features the initials IRB (Ian Rank-Broadley). The initials are mandatory. An otherwise identical coin without those initials is not specified. Eighth, clause 4 provides that these specifications do not affect any other determination. This means multiple $1 coins with different designs may all be current simultaneously. A person receiving a $1 coin with the Magic Pudding design under Item 5 cannot refuse it on the basis that it is not a standard circulating $1 coin; it is equally legal tender.

For the Royal Australian Mint, compliance is a matter of production quality control. Each of the 15 items must be struck to the exact specifications in Schedule 1. The Mint must ensure that the silver used for items 1 through 4, 7, 9, and 11 is at least 99.9 per cent pure, that the gold for items, 6, 8, and 15 is at least 99.9 per cent pure, and that the gold for the $10 coin (Item 15) is at least 99.99 per cent pure. The base metal $1 coins in items 5, 12, and 13 must be made of copper, aluminium and nickel, but the proportions are not specified, so the Mint can use its standard circulating coin alloy. Weight control is critical: each coin must fall within the stated allowable variation from the standard weight. The Mint should calibrate its weighing equipment to detect coins that are below the minimum or above the maximum. For the silver $5 coins, the acceptable range is 35.77 to 36.85 grams. Coins outside that range should be rejected and not issued. Dimensional tolerances are given as maximums. The diameter and thickness are stated as maximums rather than targets. For the silver $5 coins, the maximum diameter is 38.94mm and maximum thickness is 3.50mm. Any coin below those maximums is acceptable, but any coin that exceeds them is non-conforming. The Mint should set its tooling to avoid exceeding the maximums. The edge type must match exactly: continuously milled for some items, and 14 alternating milled and plain segments for the $1 coins. The design details must be reproduced exactly, including all inscriptions and the placement of the denomination. Items 4, 14, and 15 require the denomination on the obverse as well as the reverse. Items 12 and 13 include variations in the year inscription and the inclusion of single letters (A, B, C, M, S, H, P) on the reverse of Item 12. For dealers and collectors, compliance means verifying that a coin matches the specification before treating it as an authorised coin. For dealers, this is a commercial necessity. Selling a coin that does not match the specification risks liability for misleading conduct under Australian Consumer Law. Dealers should weigh coins, measure them, and visually inspect the design details. The weight is the most objectively verifiable attribute. A digital scale accurate to 0.01 grams can confirm whether a coin falls within the allowable variation. The dimensions can be checked with callipers, though the maximum tolerances mean that any coin within a reasonable range is likely compliant unless it is clearly oversized. The edge type and design details require visual inspection. For a collector acquiring these coins as an investment, particularly the precious metal pieces, independent verification by a grading service or a bullion dealer provides assurance. The collector should also be aware that the face value is not the market value. A silver $5 coin contains silver worth many times $5, so its value tracks the silver price, not the denomination. The specification ensures the metal content, but the collector bears the market risk of precious metal price fluctuations. For anyone receiving one of these coins in payment, which is unlikely for the precious metal pieces but possible for the base metal $1 commemorative coins, the coins are legal tender and must be accepted for debts up to the applicable limit. The recipient can verify the coin by comparing it to the published Schedule on the Federal Register of Legislation. The long term compliance strategy for the Mint is to maintain these specifications on the register until the coins are no longer produced, and to issue a new determination when new designs are required. For the market, the existence of a public specification reduces information asymmetry and allows private verification, which is a benefit for trade in these coins.
