Currency (Royal Australian Mint) Determination 2004 (No. 2)

The determination introduces several concepts drawn from the Currency Act 1965. The most important is standard composition. This is the prescribed metal or alloy from which the coin must be made. For the base‑metal $5 coin, the composition is a mixture of copper, zinc, aluminium and tin - a common blend for commemorative coins, though not as corrosion‑resistant as cupro‑nickel. The silver $5 coin requires “at least 99% silver”, meaning the coin may contain up to 1% other metals (often copper as a hardening agent). The $50 coin uses three distinct compositions for each ring: outer ring “at least 99.9% copper”, intermediate ring “at least 99.9% silver”, and centre “at least 99.9% gold”. These high‑purity requirements for silver and gold are typical for investment‑grade bullion coins, but the $50 face value is far below the intrinsic metal value, so the coin is not intended for circulation as $50.

Standard weight and allowable variation is another key concept. Each coin has a target weight and a permitted tolerance. The base‑metal $5 coin is 20.00 g ± 0.50 g. The silver $5 coin is 36.31 g ± 0.64 g. The $50 coin is more complex: the outer ring is 15.32 g ± 0.30 g, the intermediate ring 13.39 g ± 0.25 g, and the centre 7.80 g ± 0.10 g, with a total coin mass of 36.51 g ± 0.65 g. The tolerances are tight but allow for normal manufacturing variation. A coin falling outside the allowable variation in weight would not conform to the specification and therefore would not be a validly issued coin under this determination. The Currency Act 1965 does not automatically make such a coin illegal tender, but it would become a defective coin and the Mint would typically withdraw or not issue it.

Dimensions are given as maxima: maximum diameter 38.90 mm for all three, and maximum thicknesses of 2.65 mm (base $5), 3.50 mm (silver $5) and 3.50 mm ($50). There is no minimum diameter or thickness; a coin that is slightly smaller than the maximum but still meets weight tolerances could be accepted provided it otherwise conforms. However, for the tri‑metal $50 coin, the individual rings must fit together - a diameter significantly below the maximum might cause the rings to misalign. The design includes both obverse and reverse elements, including text, images, colour (on the base‑metal $5) and a hologram (on the silver $5 and $50). The presence of colour and hologram raises issues of long‑term durability, as these additions are not typical for circulating coins and may wear, fade, or detach. The determination provides no guidance on what happens if the design deteriorates; presumably the design must be present as specified at the time of minting.

Shape and edge are also specified: all coins are circular with a continuously milled edge. There is no edge lettering or reeded edge pattern other than continuous milling. The denomination is set as $5 or $50, which establishes the legal tender value, but the determination does not address whether the Mint sells these coins at face value or at a premium - in practice, commemorative coins are sold at prices reflecting metal content, production costs and collector demand.

The primary entity affected is the Royal Australian Mint, which must manufacture coins that conform exactly to every specification in Schedule 1. The Mint’s production processes, quality‑control procedures, and supply chain management must ensure that the correct alloys, purities, weights, diameters, thicknesses, and design details (including colour and hologram application) are achieved within the stated tolerances. Any deviation could lead to the coins being rejected by the Mint’s own internal compliance systems, or - if they enter the market - could cause confusion about their authenticity or legal tender status. The Mint also must manage the licensing of the AOC logo and the use of the Queen’s effigy, though that is handled outside this determination.

Collectors and investors are directly affected because they rely on the specifications to determine authenticity, grade, and value. A coin that matches the determination exactly is a genuine Mint‑issued piece; one that does not may be a counterfeit, a mint error, or a later restrike not covered by this determination. The weight tolerances, in particular, are used by coin graders to assess whether a coin is within mint specifications; coins that are underweight may be considered damaged or worn, while overweight coins are extremely rare but possible. The presence of colour and hologram also affects grading - any degradation reduces the coin’s appeal and market price.

The Australian Olympic Committee (AOC) is indirectly affected because its logo appears on Australian legal tender. The determination does not evidence any licensing arrangement, but the inclusion of the AOC logo (in colour or hologram) would require permission. The AOC benefits from the publicity and recognition, but may also face reputational risk if the coins were to be counterfeited or poorly manufactured.

The public generally has little interaction with these coins, but anyone who receives one as change or as a gift is entitled to treat it as $5 or $50 in legal tender. However, given the face value versus metal content, most recipients would hold the coins rather than spend them, making them effectively non‑circulating. The determination also affects banknote and coin‑handling businesses (vending machine operators, cash‑in‑transit firms, banks) to the extent that these coins might be deposited or used in transactions. The large diameter (38.90 mm) and weight (up to 36.5 g) mean these coins do not fit standard coin‑counting equipment, so they would be treated as odd‑size pieces.

The Treasurer and the Parliamentary Secretary to the Treasurer (who signed this determination) have the statutory power to approve coin specifications. This determination is an example of delegated legislation that allows the executive to update coin designs without amending the Currency Act.

Duty of the Mint. The Royal Australian Mint must produce coins that comply with each specification in Schedule 1. This is a statutory obligation flowing from the Currency Act 1965 and the determination made under it. The Mint must also ensure that any coins it issues are within the allowable weight variation and have the correct composition, dimensions, and design. If a coin fails to meet one of these parameters, it is a non‑conforming coin. The Mint has the discretion to withhold such coins from issue or to destroy them. The determination does not prescribe how compliance is to be verified, but typical Mint practice includes batch sampling, X‑ray fluorescence analysis for composition, weighing, dimensional gauging, and visual inspection. The Mint also has a duty to maintain records that demonstrate compliance, though the determination does not explicitly require record‑keeping.

Rights of the public. Members of the public have the right to use these coins as legal tender for their face value ($5 or $50) in any transaction, subject to the limitations in the Currency Act 1965 (e.g., a creditor can refuse coins if the amount exceeds prescribed limits per denomination). The public also has the right to rely on the specifications when assessing whether a coin is genuine. If a person receives a coin that appears to match the description, they may assume it is legal tender. However, the determination does not create a private right of action if a coin is defective; any recourse would be against the Mint or the seller under contract or consumer law.

Rights of the Mint. The Mint has the right to produce and issue these coins in accordance with the determination. It also has the right to refuse to issue coins that do not meet specifications. The Mint may also alter the specifications by making a new determination (subject to the Legislation Act 2003 and gazettal).

No duties on general public. Apart from the general duty not to counterfeit or deface coins (which arises from the Currency Act, not this determination), the public has no compliance obligations under this instrument. Collectors and dealers are free to trade the coins as they wish, but they cannot alter the coins in a way that would make them non‑conforming and then represent them as genuine, as that could amount to fraud or passing off.

Rights of the AOC. The AOC’s logo is included in the design, giving the organisation visibility and possibly a commercial benefit if the Mint pays a royalty. The AOC may have contractual rights to approve the design and to ensure the logo is used correctly. The determination does not address these rights; they arise from separate agreements.

This determination itself does not create any penalties. Enforcement of coin specifications is indirect, through the Currency Act 1965. Under section 15 of that Act, a person who makes, issues, or possesses a coin that is not legal tender with the intent that it be used as money is liable to a fine or imprisonment. The specifications in this determination serve as the benchmark for what constitutes a genuine Australian coin of that denomination. If a coin purports to be a $5 or $50 coin but does not match the determination (wrong composition, wrong weight outside tolerances, wrong design), it may be considered counterfeit or an altered coin. The determination would be used as evidence in any prosecution.

Offences under the Currency Act. Counterfeiting Australian coins is punishable by up to 10 years imprisonment (section 15). Clipping, filing, or otherwise altering a genuine coin to extract metal content is also an offence. For the $50 tri‑metal coin, the high gold and silver content creates a strong incentive for criminal alteration. The determination’s tight weight tolerances make it relatively easy to detect if a coin has been tampered with, because even a small loss of metal would push the coin outside the allowable variation.

Enforcement agencies. The Australian Federal Police and the Royal Australian Mint’s security unit would handle counterfeiting matters. The Mint also has its own compliance and quality control functions; if it discovers that a batch of coins does not meet the specifications, it may recall or destroy the coins. There is no external regulator overseeing the Mint’s compliance with this determination, but the Mint is subject to audit by the Auditor‑General and parliamentary scrutiny. A failure to produce compliant coins could lead to administrative consequences (e.g., replacement of defective coins at the Mint’s cost) but not criminal penalties for the Mint itself.

Civil liability. If a consumer purchases a coin that later turns out to be non‑conforming (e.g., the colour fades immediately or the coin is underweight), the buyer may have a claim against the Mint or the selling agent under the Australian Consumer Law for misleading conduct or failure to meet consumer guarantees. The determination sets the objective standard; if the coin does not live up to it, the seller may be liable.

The determination is made under the Currency Act 1965 and is part of a broader framework of coin specifications. Other determinations under the same Act specify different coins (e.g., circulating coins, other commemorative issues, bullion coins). Section 4 of this determination expressly states that the specifications in Schedule 1 “do not affect any other determination of the specifications of a coin”. That means these three coins coexist with all other coin types; each determination stands on its own. There is no hierarchy or consolidation.

Interaction with the Legislation Act 2003. This determination is a legislative instrument that was required to be registered on the Federal Register of Legislation and was gazetted. It is subject to disallowance by either house of Parliament within 15 sitting days after tabling (though the time has long passed). It must also be periodically reviewed as part of the sunsetting regime under the Legislation Act 2003; however, given its age (2004), it may have already sunsetted if not remade. (The source text does not indicate sunsetting status; the instrument is provided as‑is.)

Interaction with intellectual property law. The designs include the AOC logo, which is a registered trademark of the Australian Olympic Committee. The determination itself does not grant permission to use the logo; that would be covered by a separate licence. The inclusion of the logo on a legal‑tender coin is unusual but permissible with appropriate authority. The effigy of Queen Elizabeth II is subject to royal copyright and approval by the Royal Mint Advisory Committee; the determination does not override those requirements.

Interaction with the Reserve Bank Act 1959 and Currency Act 1965. The Reserve Bank of Australia has the sole right to issue Australian banknotes, but coin production and issue is vested in the Royal Australian Mint under the Currency Act. The determination does not alter those arrangements. The word “currency” in the determination’s title refers to coinage, not the broader monetary system.

Interaction with state and territory laws. The determination is a Commonwealth instrument and overrides any inconsistent state or territory law regarding coin specifications. For example, no state can declare a coin with different specifications to be legal tender.

Interaction with the Competition and Consumer Act 2010. If the Mint misrepresents the specifications of a coin, it could be liable for misleading or deceptive conduct. The determination provides a clear reference standard; any claim that a coin is “as specified in the determination” must be true.

The source text does not include any amendment history. The determination was made on 17 February 2004 by Ross Cameron, then Parliamentary Secretary to the Treasurer, and was notified in the Gazette (date unspecified but the instrument commences on that date). It is designated “No. 2” for 2004, indicating there was at least one earlier determination in 2004 (presumably Currency (Royal Australian Mint) Determination 2004 (No. 1)), but that instrument is not provided.

Since 2004, the Royal Australian Mint has issued many subsequent coin specification determinations for other commemorative coins, including for later Olympic Games (e.g., Beijing 2008, London 2012). It is common for the Mint to issue a new determination each time it releases a new coin type or a new design for an existing denomination. This particular determination likely remains in force unless specifically repealed, but its practical effect is limited to the coins described: once all coins of these types have been minted and issued, the determination becomes effectively dormant. It may still be relied upon to verify the authenticity of those coins.

No amendments are listed in the provided text, and no amending instruments are referenced. Given that the determination is a one‑off specification for specific commemorative coins, it is unlikely to have been amended; amendments would typically be made by a new determination, not by amending an old one. The Legislation Act 2003 requires legislative instruments to be kept up‑to‑date on the Federal Register, but no notes indicate whether this determination has been varied.

There is no litigation history provided in the source, and it is extremely unlikely that this specific determination has ever been the subject of court proceedings. Coin specification determinations are essentially technical administrative instruments; they are not usually litigated unless a counterfeiting case turns on whether a coin meets the specifications, or if the Mint is challenged over the validity of its issuance. Neither scenario appears in public records.

If a case were to arise, the determination would be admissible as evidence of what constitutes a genuine $5 or $50 coin of the relevant issue. A defendant charged with counterfeiting might argue that a coin they produced is within the allowable variation or that the design differs only immaterially. The court would then apply the determination strictly: if the coin’s weight falls outside the tolerance, or the composition is different, or the hologram is missing, the coin is not a genuine Australian coin.

Potential civil litigation could involve the AOC if the logo were used without authorisation, but that would involve the intellectual property licence, not the determination itself. There could also be consumer claims if a coin is sold as mint quality but fails to meet the specifications (e.g., the colour flakes off). The determination sets the baseline; any deviation could support a claim of defective goods.

No case law is known to interpret this determination, and none is cited in the source. The determination is simply applied by the Mint and collectors as a factual matter, not a contested legal question.

Several aspects of this determination warrant close attention.

Weight tolerances are tight and must be applied per component for the $50 coin. The $50 coin has separate weight tolerances for the outer ring, intermediate ring, and centre, as well as a total mass tolerance. A coin could be within total tolerance but have one ring outside its individual tolerance, making it non‑conforming. This creates a strict compliance standard. The tri‑metal construction also introduces assembly risks: if the rings are not precisely aligned, the coin may be within diameter but off‑centre, affecting the design.

The $5 silver coin is only “at least 99% silver”, not 99.9%. This leaves 1% that could be any metal (typically copper). That alloy is less pure than the silver used in the $50 coin’s intermediate ring (99.9%). For investors, this matters: the $5 silver coin is not investment‑grade bullion, whereas the $50 coin has gold and silver rings that are 99.9% pure. The lower purity may also cause faster tarnishing.

Design elements - colour and hologram - have no durability specification. The determination specifies that the AOC logo on the base‑metal $5 coin is “printed in colour” and on the silver $5 coin is “in a hologram”. It does not set any standard for colour fastness, adhesion, or hologram retention. Over time, colour may fade or scratch off, and holograms may delaminate. A coin that has lost its colour or hologram no longer matches the design specification, even if weight and composition are correct. The Mint would likely consider such a coin as non‑conforming if returned, but there is no legal requirement for the Mint to replace it. This is a hidden risk for collectors.

Maximum diameter and thickness only are specified, not minimums. A coin could theoretically be smaller in diameter or thinner than the maximum, yet still meet the weight tolerance (if it is denser or thicker in another dimension). In practice, the Mint would use dies to produce uniform coins, but if a die is worn or mis‑aligned, a coin might fall short of the maximum diameter. Such a coin would still be within the specification because the spec only sets an upper limit. That could lead to variations across batches.

No specification for edge inscription or reeding. The edge is “continuously milled”, which means a pattern of parallel ridges all around. That is common, but there is no edge lettering or unique feature to prevent counterfeiting. The lack of a raised edge or security feature may make these coins easier to counterfeit than some modern coins that incorporate micro‑engraving or lathe‑cut patterns.

The determination does not prescribe the coin’s finish (proof or uncirculated). The designs could be struck in either finish, and there is no requirement that the Mint mark the coin with its year or mint mark beyond “AUSTRALIA 2004”. The obverse design includes “2004”, so the year is fixed. Later restrikes with a different year would require a new determination.

Legal tender limits still apply. While these coins are legal tender, the Currency Act 1965 limits the amount of $5 coins that can be used in a single transaction to 10 times the face value ($50) unless the recipient agrees otherwise. For $50 coins, the limit is 20 times face value ($1,000) unless agreed. Many people assume commemorative coins can be used for any amount; they cannot.

The AOC logo inclusion may create a perception of official AOC endorsement for the Mint’s product. The AOC licence may have restrictions on how the logo is used, but the determination does not mention any licence. If the AOC later objects, the determination would not be invalid, but the Mint could face a civil claim.

For the Royal Australian Mint. Compliance begins with procurement of raw materials that meet the purity specifications: “at least 99.9%” for silver and gold in the $50 coin, “at least 99%” for silver in the $5 coin, and the four‑metal blend for the base‑metal $5 coin. The Mint must verify incoming metal through assay or certification. Manufacturing processes must be calibrated to achieve the target weights within the allowable variation. For the $50 coin, individual ring production must be controlled separately, and assembly must ensure a secure fit without gaps. Quality‑control checks should include:

• weighing each coin (or a statistical sample) against the standard weight and tolerance;
• X‑ray fluorescence or other analysis of composition, especially for the gold and silver rings;
• dimensional gauging of diameter and thickness (maximums);
• visual inspection of obverse and reverse designs, including colour and hologram quality;
• edge inspection to confirm continuous milling.

Records of production runs, including rejection rates and deviation reports, should be kept for traceability. The Mint should also maintain a master specimen of each coin as a reference.

For dealers and collectors. There is no legal obligation to verify compliance, but due diligence is prudent. When purchasing one of these coins, check the weight on a calibrated scale; the tolerance is fine enough that a scale accurate to 0.01 g is desirable. Measure the diameter with callipers - 38.90 mm is the maximum, so a coin that is 38.80 mm might still be compliant but a 39.00 mm coin would exceed the spec. Verify the composition by weight or by non‑destructive testing if possible. Confirm the design details: the AOC logo should be coloured on the base‑metal $5 and a hologram on the others. If any feature is missing or degraded, the coin may be a fake or a damaged piece.

For sellers. Anyone offering these coins for sale should represent them accurately. If a coin is advertised as “as specified in the Currency (Royal Australian Mint) Determination 2004 (No. 2)”, the coin must match that determination. Sellers should be aware that coins that have been polished or have lost their colour may no longer comply, and selling them as such could breach the Australian Consumer Law.

General public. If you happen to receive one of these coins, you are entitled to use it as $5 or $50, but you should be aware of the legal tender limits. If you believe the coin is defective, you may return it to a bank or to the Mint (though the Mint is not obliged to replace a worn coin). There is no compliance obligation beyond not counterfeiting or altering it.
