Currency (Royal Australian Mint) Determination 2010 (No. 5)

The Determination operates through three interrelated mechanisms: statutory delegation, specification by schedule, and symbolic shorthand. First, the instrument is an exercise of delegated legislative power under the Currency Act 1965, namely subsection 13A(1), which the Assistant Treasurer invokes. The instrument does not repeat the enabling Act’s text or broader purposes; it confines itself to technical specification. The instrument’s sections are short and functional: s 1 names the Determination, s 2 fixes commencement, and s 3 sets out the effect of Schedule 1. The Schedule is where substantive content resides.

Second, Schedule 1 uses a table format in Part 1 to pair denominations with physical and design specifications. For each listed denomination the table records "standard composition", "standard weight and allowable variation (g)", "maximum diameter (mm)" and "maximum thickness (mm)", and design features coded by symbols for shape, edge, obverse and reverse. For example, Item 1 records the 20 cent denomination as "Copper and nickel", weight "11.30 ± 0.33", maximum diameter "28.65 mm", maximum thickness "2.52 mm", shape symbol "S1", edge "E1", obverse "O1" and reverse "R1" (Schedule 1 Part 1). Item 3 is a $1 coin with "At least 99.9% silver", weight shown in the table (Schedule 1 Part 1), shape "S1", edge "E3", obverse "O3" and reverse "R3". Part 2 decodes the symbols S1/S2, E1/E2/E3, O1/O2/O3, R1-R4 into plain-language descriptions, for example S2 as "Dodecagonal", E3 as "14 segments, of which 7 are milled and 7 are plain", O1 as an obverse with an effigy of Queen Elizabeth II and initials 'IRB' plus a representation of cricket ball stitches, and R1 as a reverse showing the six stitches of a cricket ball and an urn between a lion and a kangaroo above two cricket bats, with the words 'TWENTY CENTS' and 'THE ASHES' (Schedule 1 Part 2).

Third, the instrument limits its operation to the specified items, and explicitly preserves other determinations under the same enabling power (s 3(2)). The table and symbol decoding together function as a binding specification: the geometrical tolerances (standard weight ± allowable variation, maximum diameter and thickness) and visual elements (obverse/reverse descriptions) are the precise outputs of the statutory delegation.

Conceptually, therefore, the Determination is a technical rulemaking instrument that translates a ministerial power into enforceable manufacturing tolerances and design prescriptions. It is not an amending Act, it does not purport to create offences or administrative penalties itself, nor does it alter denominations in the Schedule to the Currency Act 1965; instead, it prescribes how specified denominations are to be made. The Note at the end directs readers to FRLI for registration details, indicating the instrument is a legislative instrument subject to the usual publication and accessibility regime.

The Determination affects a distinct set of actors because it prescribes how certain coins must be produced and what they must look like. Primary affected actor: the Royal Australian Mint as producer, because the Determination imposes the manufacturing specifications it must follow for the listed coins. The Royal Australian Mint is not named explicitly as the obliged party in the operative text, but the Determination’s title and context indicate it is the Mint’s output that is specified, and the instrument is made "for a coin having the denomination and standard composition mentioned in the item" (s 3(1) and Schedule 1 Part 1).

Second, the Assistant Treasurer (the decision-maker) is an immediate actor for legal accountability, because the instrument is made by Bill Shorten, Assistant Treasurer, under s 13A(1) of the Currency Act 1965. That identifies who decides to implement these specifications at the time of declaration.

Third, downstream private-sector actors who use, process, test or depend on coins will be affected by changes or specifications in dimensions, weight tolerance, shape or design. The Determination lists maximum diameters and thicknesses, weight and allowable variation, and shape (for example dodecagonal for the 50c coin), all factors that determine mechanical and electronic acceptance by coin-handling equipment. Accordingly, manufacturers and operators of coin-accepting devices (vending machines, parking meters, gaming machines, laundries), cash-handling businesses, banks, armored couriers and coin-sorting equipment suppliers will need to calibrate hardware or maintain acceptance profiles consistent with the specified tolerances.

Fourth, government entities involved in currency policy, cash logistics and law enforcement will be affected insofar as the physical characteristics of circulating coins change the practicalities of transport, storage and detection of counterfeits. The instrument specifies obverse and reverse designs, including commemorative reverses (for example R1 'THE ASHES', R2 'AUSTRALIA DAY 2011', R3/R4 '100 YEARS OF AUSTRALIAN COINAGE'), which impacts collectors, dealers and institutions that catalogue coins.

Fifth, consumers and businesses that receive coins as payment are indirectly affected because coin dimensions, weight and design determine coin recognisability and machine acceptance. While the Determination does not on its face create obligations for recipients, their practical experience of coins depends on adherence to the table.

Finally, regulatory and legal advisers, compliance officers and procurement officials who manage coin-operated systems or the supply chains for coin-accepting devices face compliance and testing tasks to ensure current equipment correctly identifies and sorts coins conforming to the new or specified tolerances.

The Determination does not itself create statutory duties for these downstream actors, but by setting the physical characteristics of coins it changes the inputs those actors must accept and adjust to. Section 3(2) allows coexistence with other determinations, meaning equipment suppliers must be prepared for multiple specifications to be in circulation concurrently.

The Determination establishes duties by specification rather than by prescriptive command phrased as "you must". Its operative duty is directional and technical: for each listed denomination, "each item in Schedule 1 specifies" the required standard weight, allowable variation, dimensions and design for coins of that denomination (s 3(1)). Practically this places a technical compliance duty on the coin manufacturer to produce coins that conform to those specifications, because the instrument expressly defines those parameters for coins to which the Schedule applies.

Rights are not articulated as entitlements in the instrument. The Determination does, however, preserve existing determinations by declaring it "does not affect any other determination of the standard weight, allowable variation, dimensions and design of a coin made under subsection 13A(1) of the Act" (s 3(2)). That preservation can be read as ensuring that coins authorised by earlier determinations remain valid, enabling the Royal Australian Mint to lawfully produce multiple variants concurrently. For downstream actors this creates a de facto right to encounter coins with different allowable specifications simultaneously, because the instrument foresees coexistence.

Key technical duties derived from the Schedule include compliance with:

• Composition: the table sets "standard composition" for each listed denomination (for example "Copper and nickel" for 20c and 50c; "At least 99.9% silver" for one $1 item; "Copper, aluminium and nickel" for the other $1 item) (Schedule 1 Part 1). The producer must meet these composition standards.

• Weight and tolerance: for each item a "standard weight and allowable variation (g)" is prescribed, for example 20c "11.30 ± 0.33" and 50c "15.55 ± 0.40" (Schedule 1 Part 1). Manufacturing tolerances must fall within the allowable variation.

• Dimensions: maximum diameter and maximum thickness are specified (Schedule 1 Part 1). Coins must not exceed these maxima.

• Shape and edge: the symbolic codes S1/S2 and E1/E2/E3 denote shape (circular or dodecagonal) and edge treatment (continuously milled, plain, or segmented 14 parts), all of which are binding design parameters (Schedule 1 Part 2).

• Design: obverse and reverse designs are specified in words for each symbol code O1-O3 and R1-R4 (Schedule 1 Part 2). Those descriptions include inscriptions and pictorial elements such as effigies and commemorative motifs, and therefore define what elements must appear on coin faces.

Because the Determination is a legislative instrument, the principal duty is to manufacture coins in accordance with the Schedule. The Determination contains no express private rights to challenge particular coins, no appeals mechanism, and no set penalty clauses in the instrument itself. Any legal rights, enforcement powers or sanctions arising from contraventions of these specifications must be found in the Currency Act 1965 or other laws, not in the Determination text presented here. The instrument’s Note directs users to the FRLI for registration details, which is relevant for legal availability and public notice.

The Determination does not include any penalty provisions, enforcement mechanisms or compliance processes within its own text. It is a technical specification instrument; there are no express offences, pecuniary penalties, or administrative sanctions contained in the sections or Schedule provided. The Determination repeatedly frames itself as a specification: s 3(1) states each item in Schedule 1 "specifies" the standard weight, allowable variation, dimensions and design, and s 3(2) clarifies it does not affect other determinations. The Note at the end directs readers to the FRLI for registration, but gives no enforcement guidance.

Given the absence of enforcement provisions within the Determination, parties seeking to know how compliance is monitored, who inspects minted coins, or what penalties follow manufacture of nonconforming coins must look to the Currency Act 1965 and any relevant administrative practice at the Royal Australian Mint or within Treasury. The Determination identifies the enabling power as subsection 13A(1) of the Currency Act 1965, which implies that any powers to enforce compliance, or to penalise the making, issuing or use of unapproved coins, will be found in that Act or in related statutory instruments. The Determination itself does not reproduce the enforcement structure of the Act.

For practical purposes, enforcement can take several forms though none are stated here. First, the producer (the Mint) will have internal quality control processes to ensure adherence to the weight, diameter, thickness and design specifications. Second, third-party equipment manufacturers and businesses may detect nonconforming coins in normal use when validators reject coins outside tolerances. Third, legal or administrative action for producing unauthorised coinage, or for circulating coins that do not comply with statutory specification, would rely on the provisions of the Currency Act 1965 and possibly on other criminal or regulatory statutes, none of which are reproduced in this Determination.

Because the instrument preserves other determinations (s 3(2)), enforcement practice also needs to distinguish between lawful variants authorised by other determinations and nonconforming items. The Note's FRLI reference is relevant for stakeholders to check the registration history and any subsequent instruments that might include enforcement detail, amendments or revocations. In short, the Determination sets technical obligations but contains no stand-alone enforcement regime; the user must consult the Currency Act 1965 and the FRLI for enforcement and sanctioning mechanisms.

The Determination is explicitly made under subsection 13A(1) of the Currency Act 1965, therefore its legal status and effect are derived from that Act. Section 3(1) of the Determination ties its operation to coins "whose denomination is specified, or taken to be specified, in the Schedule to the Currency Act 1965", which links the Determination to how denominations are defined under the principal Act. Section 3(2) makes a cross-instrument interaction rule: the Determination "does not affect any other determination of the standard weight, allowable variation, dimensions and design of a coin made under subsection 13A(1) of the Act", thereby recognising that multiple determinations may operate concurrently and that this Determination is additive rather than exclusive.

The Note at the end of the Determination refers to the Federal Register of Legislative Instruments kept under the Legislative Instruments Act 2003 and gives the FRLI web address, thereby connecting this instrument to the legislative instruments regime. That linkage has several legal implications: the Determination is subject to registration and public availability requirements under the Legislative Instruments Act 2003, and its validity and any procedural defects could be assessed in the context of that Act. Stakeholders should therefore consult FRLI for the registered instrument and any associated tabulated metadata, commencement particulars, or subsequent instruments that may amend, supersede or repeal it.

Because the Determination sets physical characteristics and designs for coins, it interacts functionally with a range of non-legislative regulatory and contractual regimes. For example, manufacturers of coin-accepting devices and service providers will need to ensure that their hardware and validation software accept or reject coins in line with the prescribed maximum diameters, thicknesses and weight tolerances. Those private contractual and technical interactions are not regulated by the Determination, but they are materially affected by it.

The Determination does not itself create, vary or explain offences; any criminal or civil consequences for producing or circulating nonconforming coins will be found in the Currency Act 1965 or other statutes, not in the Determination. The instrument’s preservation of other determinations means it works alongside, rather than replacing, other legal specifications of coinage. Lastly, the Determination’s designs incorporate depictions of the effigy of Queen Elizabeth II with the initials 'IRB' and other inscriptions; any legal constraints on the use of royal effigies or on commemorative design approvals would be matters for the enabling Act or for the Ministerial or Mint approval processes, not the Determination text.

In practical terms the Determination is a technical node within a broader statutory, administrative and private-regulatory ecosystem: it is enabled by the Currency Act 1965, registered under the Legislative Instruments Act 2003 regime, and has downstream effects on private contracts and technical standards for coin-handling equipment.

The Determination itself contains no amendment schedule, no revocation clauses and no later-dated modifications within the text provided. It bears the date 26 October 2010 and a commencement mechanism in s 2 stating it "commences on the day after it is registered". The Note directs users to the Federal Register of Legislative Instruments for registration details, which is the appropriate place to look for any subsequent amendments, revocations or replacement instruments made under the Legislative Instruments Act 2003. The Determination’s preservation clause (s 3(2)) shows the drafters intended it to sit alongside earlier or later determinations.

Because the document provided is the Determination itself and not the FRLI record, the instrument does not supply a history of amendments or a versioning trail. To establish whether this Determination has been amended, superseded or repealed, an interested party must consult the FRLI entry for the Determination or the Currency Act 1965’s consolidated materials. The Note makes that procedural route explicit.

The Schedule contains commemorative designs dated 2010 and 2011 in the obverse descriptions (for example O3 includes 'AUSTRALIA 2010' while O1/O2 reference 'AUSTRALIA 2011' in the obverse inscriptions), which suggests the Determination anticipates coin issues across those years. Any changes in dates, designs, composition or tolerances introduced after this Determination would be implemented by further determinations under the same enabling subsection 13A(1). Those subsequent determinations, if any, would appear on FRLI with their own dates and amendment entries.

In short, the Determination contains no internal amendment history. The formal amendment, revocation and replacement trail is managed through FRLI and the enabling legislative framework. Users seeking a complete amendment history must consult FRLI and the Currency Act 1965 consolidation to confirm whether later instruments have modified the specifications in Schedule 1.

The Determination does not reference any case law, and the text contains no indication of litigation pertaining to its contents. There are no reported proceedings, appeals or judicial interpretations cited in the instrument. Because it is a technical legislative instrument,setting composition, weights, dimensions and designs,any litigation would arise only if contested in the courts, for example through judicial review of the instrument’s validity or through enforcement action grounded in the Currency Act 1965. The Determination itself gives no indication that litigation has occurred.

To identify any litigation that might touch on this Determination one must search court databases and the FRLI record for this instrument. The instrument’s Note points to FRLI for registration, which would include any annotations or related documents; but the Determination text here contains no litigation history. As a result, this section records the absence of litigation references in the instrument, and flags that any judicial history would need to be sourced from external legal databases or FRLI case annotations.

Practitioners seeking to challenge or rely on the Determination in litigation should therefore:

• Check FRLI for contemporaneous documents, explanatory memoranda, and registration particulars that may inform procedural compliance with the Legislative Instruments Act 2003.

• Review the Currency Act 1965 (the enabling Act) for any statutory grounds that might generate disputes about the scope of ministerial power under subsection 13A(1), including whether the specification falls within the permitted ambit of the delegated power.

• Search court records for any judicial review, administrative law challenges, or criminal prosecutions referring to coin specifications or to the manufacture or circulation of nonconforming coinage.

None of these steps are documented in the Determination itself; they are necessary because the instrument contains no litigation history or litigation-related material.

Several practical and legal "gotchas" flow directly from the instrument’s structure and content, and they are matters stakeholders should note when using the Determination.

1. Multiple $1 specifications coexist. Schedule 1 lists two different $1 items: Item 3 is a $1 "At least 99.9% silver" coin with its own weight, diameter, thickness, and design codes (S1, E3, O3, R3) while Item 4 is a $1 coin of "Copper, aluminium and nickel" composition with a different standard weight and allowable variation but the same maximum diameter and thickness in the table (Schedule 1 Part 1). The Determination, via s 3(2), does not displace other determinations. Practically, that means multiple $1 types may circulate concurrently, which has implications for coin recognition systems and for anyone attempting to reconcile coin counts by weight or by denomination.

2. Symbol-based cross-references require careful reading. Schedule 1 uses symbol codes S1-S2, E1-E3, O1-O3 and R1-R4 and only explains those in Part 2. A superficial reading of the table without the Part 2 decoding could lead to misinterpretation of shape, edge or design obligations. For example, E3 is not "plain" or "milled" but "14 segments, of which 7 are milled and 7 are plain", a specific physical feature that may present manufacturing and detection challenges (Schedule 1 Part 2).

3. Wording of obverse effigy initials. The obverse descriptions include an effigy of Queen Elizabeth II with the initials 'IRB' (Schedule 1 Part 2, O1-O3). The Determination does not elaborate on the identity behind the initials or the source of authorisation for that effigy. Users should note the instrument prescribes the initials as part of the obverse description; any change to the official effigy would require a new determination or other legal authority.

4. Precise tolerances are binding. The table specifies numerical weights and allowable variations (for example 20c "11.30 ± 0.33") and maximum diameters and thicknesses. Equipment calibrated to narrower tolerances than those specified by the Determination could erroneously reject lawful coins; conversely, equipment calibrated to accept a broader range could accept nonconforming items if other determinations are not considered. The maximum dimensions are worded as "Maximum diameter (mm)" and "Maximum thickness (mm)" in the table, which may be interpreted strictly, so manufacturers must ensure coins do not exceed these maxima (Schedule 1 Part 1).

5. Design descriptions include year inscriptions. The obverse and reverse descriptions include year-specific inscriptions such as 'AUSTRALIA 2010' and 'AUSTRALIA 2011' for certain obverses (Schedule 1 Part 2, O1-O3). That means the Determination prescribes dated designs; if a minting year differs from those specified, a procedural error may have occurred unless covered by another determination.

6. No internal enforcement or dispute mechanism. The Determination itself contains no enforcement wording. Stakeholders should not rely on the instrument for procedural remedies; they must refer to the Currency Act 1965 for enforcement or to FRLI for registration and any explanatory materials.

7. Commemorative reverses and collector interest. The reverse designs (R1-R4) are commemorative or thematic,'THE ASHES', 'AUSTRALIA DAY 2011', and '100 YEARS OF AUSTRALIAN COINAGE' (Schedule 1 Part 2). These features may create coins with a collectible premium, but the Determination does not address sale, pricing, or numismatic treatment; those are commercial consequences outside the Determination’s scope.

In short, the principal gotchas are coexistence of multiple specifications for the same denomination, reliance on symbol decoding in Part 2, precise numeric tolerances that interact with private equipment calibration, dated inscriptions, and the absence of enforcement detail in the instrument itself.

Compliance with this Determination depends on the stakeholder. The Determination places the technical obligation on the coin producer to adhere to the Schedule’s specifications (s 3(1)). Below are practical compliance actions framed by category of actor, tied to the instrument’s text.

For the Royal Australian Mint (or any authorised minter):

• Adopt the Schedule 1 Part 1 parameters as production standards, ensuring each issued coin matches the "standard composition", "standard weight and allowable variation", "maximum diameter", "maximum thickness", "shape" and "edge" codes for the relevant item (s 3(1) and Schedule 1 Part 1).
• Implement quality control measures and sampling regimes to verify coin batches fall within the specified weight tolerances and do not exceed maximum dimensions.
• Ensure die and press designs capture the obverse and reverse descriptions per Part 2. For example, incorporate the obverse effigy designs with initials 'IRB' and the exact inscriptions shown in O1-O3, and create reverses that precisely reflect R1-R4 descriptions.
• Maintain production records and technical drawings that match the Schedule, to support defence against any procedural or legal challenge, and to enable quick reference in procurement or logistics disputes.
• Coordinate with Treasury or the Assistant Treasurer’s office to confirm any administrative approvals required before issuing the coins, given the enabling power is s 13A(1) of the Currency Act 1965.

For equipment manufacturers and operators of coin-accepting devices:

• Recalibrate validators and sorters to accept coins within the specified weight ranges and not to reject coins that meet the Schedule’s tolerances. For example, 20c coins should be accepted down to 11.30 −0.33g and up to 11.30 +0.33g, and so on for other denominations (Schedule 1 Part 1).
• Update shape recognition modules for dodecagonal coins (S2) and edge-detection modules for E3 segmented edges. E3 specifies "14 segments, of which 7 are milled and 7 are plain" (Schedule 1 Part 2), which requires mechanical and optical recognition profiling.
• Test machines for multi-type circulation, because s 3(2) preserves other determinations and the Schedule lists multiple $1 variants. Machines should not assume only a single $1 type exists.
• Maintain documentation of acceptance profiles and software versioning to demonstrate compliance with the current legal specifications.

For banks, cash-in-transit firms, and coin-handling centres:

• Update weighing and sorting protocols to use the Determination’s standard weights and allowable variations for reconciliation and for declaring shortages or overages.
• When mismatches occur between expected and actual weights, refer to the Schedule tolerances before treating coins as foreign or counterfeit.
• Keep abreast of FRLI entries for this Determination to detect any subsequent amendments that would change tolerances or designs.

For numismatic dealers, collectors and public-facing outlets:

• Catalogue coins using the precise obverse and reverse descriptions in Schedule 1 Part 2, including the inscriptions and motifs, and note composition differences between the silver $1 and base-metal $1 coins.
• Exercise caution when buying or selling coins whose physical properties fall close to the specified tolerances; deviations may indicate errors, altered items or potential counterfeits, but the Determination does not itself set out counterfeit definitions or offences.

For legal and compliance advisors:

• Use the Determination in conjunction with the Currency Act 1965 to advise on whether a coin as manufactured complies with statutory design and specification requirements; the Determination sets the technical standard but not enforcement or penalty mechanisms.
• Monitor FRLI for registration details, any explanatory memorandum and any subsequent determinations that might amend these specifications.

Administrative checklist, distilled from the instrument:

• Confirm the relevant item in Schedule 1 for the denomination in question (Schedule 1 Part 1).
• Verify composition language: e.g., "At least 99.9% silver" or "Copper and nickel" (Schedule 1 Part 1).
• Confirm standard weight and allowable variation numerically (Schedule 1 Part 1).
• Check maximum diameter and maximum thickness numerically (Schedule 1 Part 1).
• Decode shape, edge, obverse and reverse symbols using Part 2 and ensure designs match those full descriptions (Schedule 1 Part 2).
• Maintain production and validation records to show conformance.
• Consult FRLI for registration date and any later instruments that may amend these specifications (Note).

Because the Determination lacks its own enforcement clauses, compliance records and demonstrable quality control are the practical safeguards for producers and downstream users to show conformance to the Schedule and to the enabling legal framework.
