Currency (Royal Australian Mint) Determination 2009 (No. 6)

The central concept is the specification of a coin as the set of physical and design attributes that make a coin lawful currency under the Currency Act. The Determination specifies for each coin: denomination, standard composition, standard weight, allowable variation (tolerance), maximum diameter, maximum thickness, shape, edge finish, and obverse and reverse designs. These specifications ensure uniformity and enable verification of authenticity. Allowable variation is a critical concept: a coin that falls within the stated weight tolerance is still a valid coin; one outside that range might be considered defective or not legal coinage under the Act. The instrument creates two distinct $1 silver coins with different weights (31.635g vs 32.39g) and different tolerances (±0.50g vs ±0.80g), even though both are described with the same composition and almost identical designs. This raises questions about whether they are intended for different purposes (e.g., one for bullion investment and one for collector sets) or whether the Mint simply adjusts specifications over time. The concept of standard composition , “at least 99.9% silver” or “at least 99.99% gold” , means the coins may exceed that purity, but they must meet the minimum fineness. This is consistent with bullion coin practice where the exact purity is often guaranteed. The design is specified in great detail, including inscriptions, effigy, monogram, and artist’s representation. The obverse design includes the year “AUSTRALIA 2010” despite the Determination being dated 2009; the year on the coin is the intended year of issue, not the year of the instrument. The reverse design includes a designer’s mark “WP” (for sculptor Wojciech Pietranik), and a depiction of a Yellow-Footed Rock-Wallaby with spinifex. The use of a fixed design gives the coins collectable value and prevents unauthorised alteration. Another important concept is that the Determination is a legislative instrument under the Legislative Instruments Act 2003. This means it is subject to parliamentary scrutiny, disallowance, and sunsetting (though sunsetting typically occurs after 10 years; this instrument may no longer be in force if not remade). The note in the Determination states that all legislative instruments are registered on the Federal Register of Legislative Instruments, conferring legal effect from the date of registration. The concept of “does not affect any other determination” means this is one of multiple possible determinations under s 13A. Separate determinations may specify coins with different denominations, compositions, or designs. This Determination creates three new coin types in addition to any already existing. Finally, the coins are legal tender for their face value under the Currency Act (s 16), but the Act itself sets limits for small payments (e.g., $5 limit for silver coins) and these coins, being silver or gold, would be subject to those limits unless specifically exempted. The Determination does not mention any exemption, so the standard legal tender limits apply.

The primary entity affected is the Royal Australian Mint, which is responsible for producing coins that conform to these specifications. The Mint must design and manufacture dies, blank selection, striking processes, quality control, and packaging to ensure compliance with standard weight (including allowable variation), dimensions, and design. The Determination creates a legal requirement for the Mint: if it produces coins purportedly of these types that fall outside the allowable variation or deviate from the prescribed design, those coins may not be lawful currency and could expose the Mint to enforcement action under the Currency Act (though such action is unlikely in practice). The Reserve Bank of Australia has a general role in currency distribution, but this Determination does not impose any direct duty on the Bank. The Bank may handle these coins as part of the cash system, but because they contain significant bullion value, they are unlikely to be used in routine transactions. Coin dealers, bullion traders, and collectors are directly affected because the specifications define the product they buy, sell, and trade. They rely on the standard weight and composition to assess value; the stated composition of “at least 99.9% silver” provides assurance but places a compliance burden on the Mint to ensure that each coin meets the minimum fineness. Dealers and investors benefit from having precise official specifications that facilitate verification and reduce counterfeiting risk. Businesses and the general public are affected in theory: these coins are legal tender for their face value, so a shop could be offered a $1 silver coin as payment for $1 worth of goods. However, because the silver content is worth many times the face value (the silver price at writing is roughly A$40 per ounce, making a 31.635g coin worth about A$40 in silver), such coins will almost never be used as everyday currency. They are instead hoarded, melted (though melting Australian currency coins is prohibited without permission), or sold at a premium. The Determination therefore has negligible effect on most businesses, but it does affect the collector community who seek coins of specific designs and dates. Tax authorities are indirectly affected because the coins’ classification as legal tender may affect GST treatment. Precious metal coins that are legal tender are generally input-taxed for GST purposes, which is a concession relative to investment-grade bullion. The Determination explicitly sets the composition and weight, which are prerequisites for that tax treatment. Competitors in the bullion market (e.g., private mints, Perth Mint) may be affected because the Royal Australian Mint now offers government-guaranteed silver and gold coins that compete with other bullion products. The Determination lowers barriers for the Mint to issue these coins, which may reduce market share for private issuers, but it also provides an independent specification that the private market may use as a benchmark.

The Determination imposes a single explicit duty: the Royal Australian Mint must produce coins that conform to the specified standard weight (including the allowable variation allowed for weight tolerances), dimensions, and design. The duty arises from s 13A(1) of the Currency Act, under which the Assistant Treasurer may determine specifications, and the Mint then must follow those determinations when striking coins. The instrument itself does not state a penalty for non-compliance, but the Currency Act makes it an offence to produce a coin that does not comply with the Act or determinations, or to possess such a coin with intent to issue it (s 23). Therefore, the Mint and its officers have a legal duty to ensure that each coin of these types meets the specifications. The allowable variation is a right of the Mint: it may produce coins that fall within the weight tolerance and still be lawful. For example, the $1 silver coin in Item 1 may weigh anywhere between 31.135g and 32.135g. This allowance reduces production costs by accepting minor variability. The rights of individuals are derivative. Holders of these coins have the right to use them as legal tender for their face value, subject to any limits in the Currency Act (s 16 limits payments in silver coins to $5 unless both parties agree otherwise). Since these are bullion coins, the right to use them as tender is largely theoretical. Holders also have rights to sell the coins at market value, subject to any prohibition on melting (s 40 of the Currency Act prohibits the defacing or destruction of currency, including melting, without Ministerial approval). The instrument does not grant any right to redeem the coins at face value from the Mint or the Reserve Bank; that would be determined by other policies. The right of the Mint to issue these coins is contingent on compliance with the Determination; if the Mint fails to meet specifications, it cannot lawfully issue them as Australian currency. The public has a right to rely on the specifications when authenticating a coin, but there is no private right of action for a coin that falls outside specifications; enforcement is by the Commonwealth.

The Determination itself creates no penalties; it is a specification instrument. Penalties arise under the Currency Act 1965 for conduct relating to unlawful coins. Under s 22 of the Currency Act, it is an offence to make, sell, or utter a false or counterfeit coin resembling an Australian coin; the maximum penalty is imprisonment for 10 years. A “false or counterfeit coin” includes one that does not meet the standard weight, composition, or design prescribed by a determination (s 23). Thus, if a coin appears to be one of these $1 silver or $10 gold coins but does not comply with the Determination (e.g., weight outside allowable variation, different metal content, or different design), it may be counterfeit. Production of a genuine coin that accidentally falls outside tolerance could technically be treated as a counterfeit if the Mint issued it, but in practice the Mint would destroy or re-melt such coins. The enforcement authority is the Australian Federal Police or the Reserve Bank’s currency integrity unit. The Determination’s specifications serve as the benchmark for authenticity. The allowable variation means that a coin within the tolerance is genuine even if its exact weight differs from the standard. This provides a safe harbour for the Mint: a coin that varies slightly is still legal. However, the tolerances are relatively wide: the $1 silver coin Item 1 has a variation of ±0.50g on a 31.635g standard (about ±1.6%), which is generous compared to many bullion coins; the Item 2 silver coin has ±0.80g (about ±2.5%). The gold coin has ±0.09g on 3.133g (about ±2.9%). These tolerances reduce the risk of accidental non-compliance but also increase the risk of counterfeit or substitute coins that fall within the tolerance but are not genuine. There is also a prohibition under s 40 of the Currency Act against defacing, mutilating, or melting an Australian coin, with penalties of a fine or imprisonment. This is relevant because the bullion value of these coins likely exceeds face value, creating an incentive to melt for silver or gold. The Determination does not exempt these coins from that prohibition. Enforcement of the no-melting rule is difficult, so many such coins may be melted regardless, removing them from the coin supply. The instrument itself is subject to the Legislative Instruments Act 2003, which requires registration and provides for disallowance by either House of Parliament within 15 sitting days of tabling. If disallowed, the Determination ceases to have effect. Non-registration would make the instrument unenforceable, but it was registered. The note in the Determination confirms compliance.

The Determination is made under the Currency Act 1965, specifically s 13A(1). It must be read together with the entire Currency Act, particularly Part III (coining and legal tender), Part IV (offences), and the Schedule to the Act (which lists denominations and standard compositions). The effect of the Determination is to add these three coin types to the list of coins that are deemed to be specified in the Schedule. The Currency Act s 13A(2) provides that a coin specified under subsection (1) is taken to be specified in the Schedule. This means the coins’ denominations are recognised as lawful. The Legislative Instruments Act 2003 governs the making, registration, tabling, and sunsetting of legislative instruments. The Determination is registered as required; its Note states that all legislative instruments are on the Federal Register of Legislative Instruments. It is subject to parliamentary scrutiny and may be disallowed. Under s 50 of the Legislative Instruments Act, legislative instruments sunset after 10 years unless remade. This Determination was made in 2009, so it would have sunsetted in 2019 unless remade or its effect was preserved. The user should check whether a later instrument superseded it or whether the coin types are now covered by a newer determination. The Criminal Code Act 1995 may apply to offences concerning counterfeiting or forgery of currency, but the Determination itself does not interact with that Code. The Competition and Consumer Act 2010 and the Australian Consumer Law are relevant because if the Royal Australian Mint markets these coins, it must not engage in misleading conduct about their specifications. The Determination provides the objective standard; any claim that a coin is 99.9% silver or 99.99% gold must match the instrument. False representations could lead to enforcement by the Australian Competition and Consumer Commission. The tax treatment of precious metal coins is governed by the A New Tax System (Goods and Services Tax) Act 1999, which treats supplies of coins that are “legal tender” as input-taxed if the coin’s value is calculated by reference to its precious metal content. The Determination’s specifications (composition, weight, purity) are used by the Australian Tax Office to determine whether a coin qualifies for GST-free or input-taxed treatment. Investment gold coins (99.99% gold) may be GST-free under the Investment Gold provision. The $10 gold coin likely qualifies. The Determination thus interacts indirectly with tax law. It also interacts with the Reserve Bank Act 1959 for the overall currency system. Additionally, the Determination expressly states it does not affect any other determination of coin specifications. This ensures that other coins authorised under different determinations remain valid. It prevents implied repeal or conflict.

There is no amendment history recorded in the source document. The Determination appears to be a standalone instrument made on 10 August 2009 and registered shortly thereafter. It has not been amended by any subsequent instrument, as no amendments or variations are mentioned in the text provided. Under normal practice, amendments to such determinations would be made by a new legislative instrument that either varies this Determination or replaces it. Given the age of the document (2009), it is possible that it has been superseded by a later Currency (Royal Australian Mint) Determination, such as a more recent number. The source does not provide any later versions or compilation notes. The user must check the Federal Register of Legislation for the current status. If no amendment or remaking occurred, the Determination would have been subject to sunset under the Legislative Instruments Act 2003, expiring 10 years after registration (likely around 2019). However, some legislative instruments may have their effect preserved or may be remade before sunsetting. The note about the “Compilation date” not shown suggests the document may be the original version only. The practical implication is that these three coin types may no longer be authorised if the instrument has expired. Even if the instrument is expired, coins already minted under its authority remain legal tender indefinitely, as their status is established at the time of issue. The only effect of expiry would be that no new coins of those specifications can be produced under this Determination. The Mint would need a new determination to continue striking the same coins. The absence of amendment history could also mean the instrument was never applied; the three coin types may have been issued only as collector items and then discontinued. The user conducting a legal analysis should not assume the instrument is still in force.

There is no reported litigation involving this specific Determination that can be derived from the source text. The document itself contains no references to any court cases, and it is a routine administrative instrument unlikely to be the subject of direct judicial review. There are no disputed words or construction issues apparent from the bare specification. Any litigation that could arise would likely be under the Currency Act, challenging whether a particular coin meets these specifications, or whether the Determination was validly made. For example, a person charged with circulating a counterfeit coin could argue the coin in question is genuine because it falls within the allowable variation. That would require expert evidence on the weight and composition of the coin compared to the Determination. The absence of litigation may reflect the limited commercial and legal significance of these specific coins; they are relatively low value and generally bought and sold by collectors who rely on the Mint’s reputation rather than court enforcement. If the Determination had been challenged as exceeding the power under s 13A (e.g., if a coin design was argued to be contrary to law), no such challenge appears in the source. The Determination is also not listed in any administrative law database as having been judicially reviewed. For purposes of this deep dive, the user should note that the Determination itself is not tested in court, so its interpretation relies on plain text and the broader Currency Act. The only potential litigation context is if the Determination were disallowed under the Legislative Instruments Act, but that is a parliamentary process, not a court proceeding. The user may need to search for any cases citing the Determination in the context of coinage offences, but the source provides no evidence. Given the specificity of the coin designs to the Yellow-Footed Rock-Wallaby, it is unlikely that any intellectual property litigation has arisen from the design, as the designs are Crown-owned. In sum, the litigation history is nil.

Several points in the Determination warrant caution. First, there are two different $1 silver coin specifications (Item 1 and Item 2) with different standard weights (31.635g vs 32.39g), different tolerances, and slightly different dimensions (diameter and thickness). Yet their designs are described in identical terms. This could cause confusion in the market: a dealer or collector may inadvertently believe there is only one $1 silver coin, and a coin that falls within one specification but not the other might be considered non-conforming. The Determination does not explain the purpose of the two items. They may be different strikes (e.g., bullion vs proof finish) but the design descriptions do not distinguish. The only distinguishing feature is the weight and dimension parameters. Anyone verifying a coin’s authenticity must check which specification applies, but there is no marking on the coin to indicate Item 1 vs Item 2. This creates a hidden ambiguity. Second, the allowable variations are relatively wide for bullion coins. The silver coin tolerance of ±0.50g or ±0.80g means a coin could vary by up to 2.5% and still be legal. This might be exploited by counterfeiters to produce coins that fall within the tolerance but use a less pure alloy; the composition is “at least 99.9% silver”, so a coin that is 90% silver but weighs within tolerance would not meet composition but the composition is not easily tested by weight alone. The enforcement relies on metal assay. The wide weight tolerance may reduce the evidentiary value of weight checks. Third, the gold coin has a thickness of 1.58mm maximum; that is very thin for a 3.133g coin, and slight variation could affect stacking or use in vending machines (though these coins are not intended for vending). Fourth, the Determination uses “maximum diameter” and “maximum thickness” rather than a specified value and tolerance. This means the coin must not exceed those maxima, but it may be smaller. For example, the $10 gold coin could be as small as 17.65mm diameter minus any amount, which is not defined. This gives the Mint discretion to make coins slightly smaller, but a coin that is too small may be suspected of being counterfeit. Fifth, the obverse design year is ‘AUSTRALIA 2010’ even though the Determination was made in 2009. This could create confusion about the authority: can the Mint issue a coin dated 2010 under a 2009 determination? Yes, because the date on the coin is a design element, not the effective date of the instrument. But if the determination sunset before 2010, would coins dated 2010 be valid? The Determination commenced in 2009 and no sunset date is stated, so they are likely valid. Sixth, the Note about the FRLI is a legislative requirement, but practitioners should verify that the Determination is still listed on the FRL. If it is not registered, it may have no legal effect. Seventh, the Determination does not specify whether these coins are legal tender for any amount or are subject to the usual limitations under s 16 of the Currency Act (payments in silver under $5). That means a business could be forced to accept hundreds of these $1 silver coins up to $5 total in a transaction, not for larger amounts. This limits their utility as payment instruments. Eighth, the milled edge is continuous, which is typical for bullion coins, but some counterfeit solutions might try to replicate that. Finally, the Determination’s standard composition says “at least 99.9% silver” without specifying the exact fineness; some bullion coins are exactly 99.9% or 99.99%. The term “at least” allows a higher purity, but the Mint may choose to use finer silver, which increases cost without adding legal obligation.

Compliance with this Determination depends on the role of the entity. For the Royal Australian Mint, compliance means ensuring that every coin it produces that is intended to be one of these three types meets the exact specifications. The Mint must implement quality control processes to check weight (within allowable variation), maximum diameter, maximum thickness, shape, edge, and design. The design is prescribed to the extent of the inscriptions and the artist’s representation; the Mint must ensure that the dies exactly reproduce the effigy, the “IRB” monogram, the designer’s mark “WP”, the wallaby, rocks, and spinifex, and the lettering. Any deviation, even stylistic, could result in a coin not complying with the Determination. However, artistic interpretation is allowed only within the description; the description is detailed but does not specify exact dimensions of the design elements. The Mint would likely rely on die design approval and sample inspection. Weight compliance can be managed by statistical sampling, but the tolerance is generous. The composition “at least 99.9% silver” requires that the Mint test the silver content of blanks before striking. For the gold coin, the purity requirement is “at least 99.99% gold”, which is a very high standard requiring refined gold. Failure to meet these purity thresholds makes the coin non-compliant. The Mint should maintain documentary evidence of batch assays. For coin dealers and collectors, compliance with the Determination primarily involves authenticity verification. A dealer who accepts these coins as genuine should check that the weight and dimensions fall within the Determination’s limits, that the design matches the description, and that the coin is not defaced. If a dealer receives a coin that appears to be one of these but is outside specifications, they should treat it with suspicion and not offer it for sale as genuine; doing so could risk prosecution for uttering counterfeit coins. For businesses that might receive these coins as payment, compliance is easier: they can treat them as legal tender for up to $5 in silver coins per transaction, but they are not required to accept them beyond that limit. Businesses should be aware that the intrinsic bullion value far exceeds face value, so accepting such a coin at face value is a windfall for the payer. Realistically, no one will use them in ordinary payments. For the public, the primary compliance issue is not to melt, deface, or alter these coins, as that would violate s 40 of the Currency Act. Even though the metal value is high, melting is an offence. If a person wishes to sell the coin, they should do so as a whole coin, not as scrap metal. Compliance with tax obligations: if a person sells these coins for a profit, capital gains tax may apply, but as legal tender the gold coin might be exempt from GST when supplied. Consultation with a tax adviser is recommended. Finally, any financial institution that handles these coins in deposits or exchanges should ensure that its staff can identify the specifications and that the coins are not counterfeits. The Determination provides objective criteria for identification.
