Currency (Royal Australian Mint) Determination 2015 (No. 2)

The instrument operates through two statutory mechanisms: insertion of denomination and composition references into the Act’s Schedule (s 5), and specification of standard weight, design and dimensions under subsection 13A(1) (s 6). The Schedule to this determination is the operational heart: Part 1 contains a table of coin specifications and Part 2 provides literal explanations of the symbol codes used in Part 1 (Schedule 1, Part 1 and Part 2).

Key technical parameters specified in Schedule 1, Part 1 include:

• Standard composition: the metal(s) from which a coin is to be made. Examples in the Schedule include copper, aluminium and nickel for $1 coins; copper and nickel for 20c and 50c coins; and “copper and nickel with gold plating” for the 50c item (Schedule 1, Part 1 table).
• Standard weight and allowable variation: a nominal gram weight plus a permitted deviation expressed in grams (for example, $1 coins 9.00 ± 0.66 g; 20c 11.30 ± 0.78 g; 50c 15.55 ± 0.96 g) (Schedule 1, Part 1 table).
• Maximum diameter or other dimension and maximum thickness in millimetres (for example, $1 maximum diameter 25.12 mm and thickness 3.46 mm; 50c maximum diameter 31.65 mm and thickness 3.16 mm) (Schedule 1, Part 1 table). The table column is explicitly headed “Maximum diameter (mm) or other dimension”, signalling accommodation of non-circular shapes (see Part 2 definitions of shape S2 for dodecagonal).
• Shape and edge: coded symbols (S1, S2 for shape; E1-E3 for edge) are defined in Part 2 (Schedule 1, Part 2 items 1-5). For example, S1 = circular, S2 = dodecagonal; E1 = interrupted milling, E2 = continuously milled, E3 = plain.
• Obverse and reverse design codes: obverse codes O1 and O2 describe effigies and inscriptions (both include an effigy of Queen Elizabeth II and specific inscriptions including “ELIZABETH II”, “AUSTRALIA”, a year and the letters “IRB”; O2 also adds Arabic numerals for the amount in dollars and two representations of a dot) (Schedule 1, Part 2 items 6-7). Reverse codes R1-R5 contain detailed textual descriptions of artwork and inscriptions, including colour elements and textual legends such as “1 DOLLAR” and “WWI-WAR HEROES” (R1), “MAGNA CARTA” and related inscriptions (R2), the Commonwealth arms and ‘50’ with designer initials ‘SD’ (R3), a coloured ornamental border and a donkey with a cross and ‘1915’ (R4), and a stylised coloured barometer and a gun containing a set of inscriptions and symbols including a stylised cat and the sequence ‘TEEL’ and ‘12149’ (R5) (Schedule 1, Part 2 items 8-12).

Structurally, the determination is narrowly focused. It makes no general legal changes to currency law beyond adding specific physical and visual specifications to be treated as part of the Act’s Schedule (s 5(2)). It also contains preservation clauses stating that it does not affect other determinations made under the same provisions (s 5(3); s 6(4)). The determination is therefore a technical addendum to the Act: it defines what those particular coins are to be, physically and artistically.

Direct decision-maker

• The determination was made by the Parliamentary Secretary to the Treasurer, acting under the delegated powers in the Currency Act (s 3; front matter identifying Kelly O’Dwyer). The statutory power to specify denominations, composition, weight, design and dimension is exercised by this instrument.

Government minting authority

• The Royal Australian Mint is the obvious administrative implementer of the specification. The instrument is titled as a "Royal Australian Mint Determination" and the Schedule provides the manufacturing specifications that the Mint must follow when producing coins (Schedule 1, Part 1 and Part 2). The determination prescribes physical parameters that the Mint is required to meet for each listed item by being treated as included in the Schedule to the Currency Act (s 5(2)).

Currency users and intermediaries

• Banks, cash-in-transit operators, retailers, vending and parking machine operators, gaming and amusement machine operators, coin-counting/recycling businesses, transport operators and other coin-processing businesses will be functionally affected insofar as the determination fixes physical dimensions, shapes, weights and edge types for legal tender coins. The Schedule’s machine-relevant parameters include maximum diameter or other dimension, thickness, weight tolerances and edge types for each coin (Schedule 1, Part 1 table). These parameters are the technical inputs used by coin-accepting machinery and counting equipment to identify and authenticate coins.

Collectors and numismatists

• The Schedule contains reverse designs with specific commemorative inscriptions and coloured representations (Schedule 1, Part 2 items R1-R5), which have implications for collectors and secondary-market pricing. The presence of multiple $1 entries with distinct reverse designs (items 1, 4 and 5 in Part 1) formalises collectible variants in the statutory Schedule.

Legal and regulatory actors

• The instrument amends the Schedule to the Currency Act (s 5(2)). Consequently, any legal analysis tied to what is the statutory specification of legal tender coins must refer to the Act as if it included these items. The determination itself does not create offences or set enforcement regimes; these remain within the Currency Act and other laws applicable to currency and counterfeiting (s 3).

Who it does not specify

• The determination does not allocate funding, specify production quantities, nor set circulation policy (it contains no provisions on issuance, ordering or distribution). It also does not contain penalties for non-compliance with the specifications; enforcement remains governed by the Act and other applicable instruments (s 5(3); s 6(4)).

Practical concentrated effects

• The most concentrated costs and operational adjustments fall on the Mint and on businesses that physically handle coins. Coin-handling equipment makers and operators are the parties most likely to incur adjustment costs if these specifications change materially from previous coin specifications. The determination itself, however, provides only the technical standards; it does not specify transitional arrangements, nor a programme for recall, redemption or replacement.

What the determination requires of the state instrumentally

• The determination imposes a duty on the State instrumentally to treat the specified denominations and compositions as included in the Schedule to the Currency Act (s 5(2)(a)-(b)). That functional duty means the Act will have effect as if it already contained those denomination references and corresponding standard compositions. It also requires the specification of standard weight, allowable variation, design and dimensions to be treated as the statutory standard for the coins listed (s 6(2)).

Duty of conformity for coin manufacture

• The Royal Australian Mint, as the manufacturing authority, must produce coins that conform to the standard composition, weight and allowable variation, maximum dimensions and thickness, shape, edge type and the obverse and reverse designs as set out in Schedule 1, Part 1 and explained in Part 2. Those are the normative technical requirements the determination sets; they are expressed in the Schedule table and symbol explanations.

Right of the public to legal-tender coins

• By incorporating the items into the Act’s Schedule (s 5(2)), the instrument effectively defines what constitutes the specified legal-tender coins in terms of physical composition and appearance. The instrument does not itself create a separate private right, but it determines the physical attributes of coins that the state will recognise as its prescribed currency units under the Act.

Limits and preservation of other determinations

• The instrument contains express non-derogation clauses: section 5(3) states it does not affect other determinations under the same paragraph, and section 6(4) states it does not affect other determinations under subsection 13A(1). Those clauses limit the instrument’s scope with respect to prior or subsequent determinations made under the same statutory powers.

No express duty on private operators

• The instrument does not create statutory duties for private persons to adjust equipment or operations. However, by fixing dimensions, weights and edges, it creates de facto operational requirements for private actors who need to accept or verify coins in commerce; those requirements are not expressed as statutory duties in the text, but as technical constraints that affect private practice.

No penalties or enforcement provisions in the text

• The determination contains no standalone enforcement, penalty, or offence provisions. Any statutory penalties for counterfeit, misuse, or non-conformity to coin specifications would be contained in the Currency Act or other legislation, not in this determination itself (cf. s 3 indicating authority under the Act, and the preservation clauses in s 5(3) and s 6(4)). The determination confines itself to specification.

Design-specific mandatory elements

• The textual design descriptions are highly prescriptive. For obverses, both O1 and O2 require an effigy of Queen Elizabeth II and specific inscriptions including “ELIZABETH II”, “AUSTRALIA”, a year in numerals and the letters “IRB” (Schedule 1, Part 2 items 6-7). O2 requires additional items, including Arabic numerals for the amount in dollars followed by “DOLLAR” or “DOLLARS”, and two representations of a dot. Reverse descriptions R1-R5 enumerate specific imagery, legends and in some cases coloured elements (Schedule 1, Part 2 items 8-12). The Mint, therefore, is required to reproduce those elements in the coin reverses and obverses specified.

Measurement tolerances and machine-readability

• Standard weights and allowable variations are set in grams and must be respected (Schedule 1, Part 1). Edge types (E1-E3) and shape (S1, S2) are specified; the combination of these prescriptions governs how coins will be recognised by mechanical and digital acceptance systems and by visually inspecting officials.

The text of this determination contains no penalty clauses, criminal or civil sanctioning language, nor any administrative enforcement mechanism. The instrument limits itself to specification and statutory incorporation functions (s 5 and s 6). The determination therefore does not itself create new offences, nor does it amend penalty provisions: any enforcement must be sought under the Currency Act 1965 or other relevant law.

Legal place of enforcement

• Enforcement and penalty regimes applicable to currency manipulation, counterfeiting, or misuse are matters for the Currency Act and related legislation. The determination was made under paragraph 13(2)(b) and subsection 13A(1) of the Currency Act 1965 (s 3). Those provisions locate the specification power in primary legislation; any sanctions for contraventions of statutory currency rules will be found in that Act and other statutes, not in this instrument.

Practical enforcement implications

• Although the instrument contains no explicit enforcement steps, it has practical enforcement effects. Once the Act is taken to include these Schedule items (s 5(2)), coins produced to these specifications are the statutory reference standards. If a coin in circulation diverged materially from the statutory specification, the divergence could be relevant in enforcement actions under the Act (for example in assessing whether a coin is genuine or counterfeit), but the determination itself does not describe that enforcement or the relevant procedures.

Administrative compliance monitoring

• The text does not establish an inspection regime, certification process, acceptance testing protocol, or periodic reporting by the Mint. It only records the specifications; ongoing compliance monitoring would be governed by administrative practice within the Mint and by broader statutory regimes, none of which are set out in this determination.

Interplay with other determinations

• The preservation clauses (s 5(3); s 6(4)) expressly state that the determination does not affect other determinations made under the same statutory paragraphs. That clause implicitly preserves other enforcement or specification instruments made under the Act, so enforcement frameworks in other determinations,if they exist,remain applicable where relevant.

No private right of enforcement created

• The determination does not create a private civil remedy for third parties to compel the Mint to comply or to challenge coin specifications; it simply sets the standards to be incorporated into the Act’s Schedule (s 5(2)). Any legal challenge or review of the determination would proceed under general administrative law channels, but the determination contains no specific procedural pathway for such challenges.

Primary statutory relationship

• The instrument is made under and operates through the Currency Act 1965. It expressly states that it is made under paragraph 13(2)(b) and subsection 13A(1) of that Act (s 3). Section 5 instructs that the Act shall have effect as if the Schedule to the Act included the references and standard compositions set out in Part 1 of Schedule 1 to this determination (s 5(2)). Section 6 provides the same incorporation mechanism for weight, design and dimension standards (s 6(2)). Therefore, the determination functions as a statutory amendment by reference: the Act, post-commencement, is to be read as if it already contained these Schedule items.

Preservation of other determinations

• The instrument makes two express non-derogation statements: it does not affect other determinations made for paragraph 13(2)(b) of the Act (s 5(3)), and it does not affect other determinations made under subsection 13A(1) (s 6(4)). Those clauses preserve the coexistence of this specification with any other specifications or determinations previously or subsequently made under the same powers, which is relevant where overlapping specifications or transitional arrangements exist in the Act’s regulatory architecture.

No amendment to offences or criminal provisions

• The determination does not amend or refer to criminal or penalty provisions; those remain in the primary legislation and other laws. Any interaction with offences for counterfeiting, misuse of coins or other related matters is therefore indirect: the determination sets the physical standards which enforcement bodies will use as references when applying the Act and other laws.

Intellectual property and authorship references

• The obverse inscriptions include the letters “IRB” (Schedule 1, Part 2 items 6-7) and one reverse carries designer initials “SD” (Schedule 1, Part 2 item 10). The determination records these textual elements but does not address copyright, moral rights, or licensing arrangements for designs. Any intellectual property rights, commissions or design contracts remain matters outside this instrument; the determination records the textual elements as part of the statutory specification only.

Technical interface with equipment and standards

• By specifying shape, diameter/other dimension, thickness, weight tolerances, and edge type, the determination provides the technical inputs that interact with standards and equipment used by industry. The instrument does not, however, amend consumer law, payments law or other technical standards; it simply fixes the coin parameters that other regulatory instruments and private contracts reference in practice.

Administrative law review and judicial interaction

• The determination is an administrative act under the powers of the Currency Act. The text contains no procedural or review provisions. Any judicial review, challenge, or interpretation would be against the statutory exercise of power under the Currency Act and general administrative law principles, not against the text of this determination alone. The determination’s own preservation clauses (s 5(3), s 6(4)) may be relevant to legal arguments about conflict with other determinations.

Transitional or ancillary instruments

• The determination does not provide transitional arrangements, recall procedures or currency-exchange mechanisms for replacing or circulating coins. Any such interaction with broader monetary or regulatory programmes would be the subject of separate administrative decisions or instruments, not contained in this document.

Document identity and date

• The instrument identifies itself as the Currency (Royal Australian Mint) Determination 2015 (No. 2) and is dated 13 February 2015 (front matter). The determination’s commencement is the day after registration (s 2). The text does not list prior versions of this specific determination within itself.

Relationship to other determinations

• The instrument contains clauses that preserve other determinations: section 5(3) says “This section does not affect any other determination made for paragraph 13(2)(b) of the Act.” Section 6(4) similarly says “This section does not affect any other determination made under subsection 13A(1) of the Act.” Those clauses indicate the drafters anticipated multiple determinations under those statutory powers and intended this instrument to sit alongside them rather than to be an exclusive or overriding instrument.

No internal amendment schedule

• The text does not provide an internal amendment log or a history of earlier amendments to the Act effected by earlier determinations. It neither repeals nor amends prior determinations by express text; it only preserves them (s 5(3); s 6(4)). To trace the full amendment history of coin specifications in the Currency Act Schedule, a reader must consult the Act and other determinations referenced under the Act; that history is not contained in this determination.

Single-purpose nature

• The determination itself is narrowly confined: name (s 1), commencement (s 2), authority (s 3), definitions (s 4), specification of denominations and composition (s 5), and specification of weight, design and dimension (s 6) plus Schedule 1 with the detailed table and symbol explanations. There are no subsequent amendments to this instrument recorded within it.

Administrative dating and maker

• The determination is signed by the Parliamentary Secretary to the Treasurer (Kelly O’Dwyer) and dated 13 February 2015 (front matter). That signing datum is the only timestamp and authority record in the instrument. The commencement provision (s 2) makes the legal start date dependent on registration, not the date of signature alone.

No retroactive or sunset clauses

• The determination contains no retroactive effective-date provision, other than commencement on registration day after, and contains no sunset clause or expiry mechanism. It is therefore intended to remain in force until amended or repealed by later determination or legislative amendment, subject to the statutory framework (s 2; s 5(3); s 6(4)).

The determination text contains no reference to litigation, court decisions, or adjudicative history. There are no citations to case law, no mentions of judicial interpretation, and no recorded judicial challenges included in the document. The instrument is a technical regulatory specification and does not include narrative or footnotes referencing litigation.

What the document does record

• The instrument records the statutory authority under which it was made (paragraph 13(2)(b) and subsection 13A(1) of the Currency Act 1965) and the maker and date (front matter), but it contains no internal record of legal disputes, reviews or challenges.

Implication for researchers

• To locate litigation that may have engaged these specifications or challenged the determination, a researcher must search judicial and administrative law records outside this instrument. The determination itself does not record any litigation outcomes, nor does it indicate whether or how frequently such determinations have been subject to legal challenge.

No internal jurisprudential guidance

• There are no interpretative aids in the instrument, such as statements of legislative intent or explanatory memoranda, nor does it cross-reference judicial decisions or administrative practice. Any adjudicative treatment of disputes over coin specifications would therefore depend on the Currency Act and on ordinary statutory interpretation applied by courts or tribunals.

Multiplicity of identical denominations

• The Schedule contains three separate table entries for the $1 denomination (Schedule 1, Part 1 items 1, 4 and 5). Each $1 entry lists the same standard composition and weight and the same maximum diameter and thickness, but different obverse and reverse codes are attached (items 1, 4 and 5). This creates multiple statutory variants of the same denomination distinguished only by design codes. Users interpreting the Act’s Schedule should note that the Act, as amended by this determination, is to be read as if it includes all these items (s 5(2)). That means there can be multiple legally specified designs for a single denomination at the same time; the instrument does not indicate exclusivity or sequencing between these variants.

Design specificity and textual oddities

• Reverse R5 contains an unusually detailed and idiosyncratic textual list: the reverse is described as including a stylised coloured representation of a barometer with specific numbers and, in the foreground, a stylised representation of a gun containing: a stylised cat, the letters ‘V’, ‘S’, ‘M’, the sequence ‘TEEL’, and ‘12149’ (Schedule 1, Part 2 item 12). The literalness and specificity of these textual elements mean the Mint must reproduce these precise inscriptions, but the document provides no explanation of their provenance, meaning or legal effect beyond inclusion in the design description. Any error in reproducing such specific inscriptions could create disputes about whether a minted coin conforms to the statutory description.

Colour on coins

• Parts of the reverse descriptions explicitly require “stylised coloured representation” (Schedule 1, Part 2 items 11 and 12). The statutory description accommodates colour elements on coins. That is operationally significant because many coin-detection machines and coin-handling processes are calibrated for monochrome metal surfaces; colour introduces a new variable. The instrument does not address tolerances for colour, nor does it set standards for how colours are to be reproduced or authenticated, so operational ambiguities may arise for equipment suppliers and operators.

Gold plating and composition

• The 50c specification is stated as “Copper and nickel with gold plating” (Schedule 1, Part 1 item 3). Gold plating over a copper-nickel core creates a layered composition that may affect magnetic, electrical and optical detection signatures used in vending and authentication systems. The determination provides the composition but does not provide testing or assay procedures. Parties relying on detection by metal composition will need to adapt to the plated construction.

Edge and shape distinctions

• The Schedule differentiates shapes and edge types: interrupted milling (E1), continuous milling (E2) and plain (E3); shapes S1 (circular) and S2 (dodecagonal) (Schedule 1, Part 2 items 1-5). The presence of dodecagonal 50c coins (S2) versus circular $1 coins (S1) is a clear mechanical discriminator. However, the table heading uses the phrase “Maximum diameter (mm) or other dimension” (Schedule 1, Part 1 table), which means for non-circular shapes the dimension may not be a simple diameter. Machine calibrations and legal interpretations may need to clarify which measurement method applies to S2 shapes.

The IRB and SD inscriptions

• Obverse designs O1 and O2 include the letters “IRB” (Schedule 1, Part 2 items 6-7) and Reverse R3 includes the designer’s initials “SD” (Schedule 1, Part 2 item 10). The instrument requires these letters on the coins, but it does not explain or authorise relevant intellectual property arrangements or the legal effect of these initials. Practitioners should note the requirement to reproduce those inscriptions exactly.

No transitional or quantity information

• The determination prescribes physical and design features but contains no transitional provisions, no instruction on replacement of earlier coin stocks, and no information on quantities for minting or supply. There is therefore a potential operational gap between legal specification and practical circulation logistics. Private sector actors cannot assume the determination includes a timetable for introduction or withdrawal of coins.

Limited textual context and absence of rationale

• The instrument contains no explanatory memorandum or legislative history within its text describing policy rationale, expected circulation mechanics, or cost implications. Evaluating the policy effects therefore depends on external documents and administrative records, not on the determination itself. Where design oddities or multiple entries for one denomination exist, the instrument does not explain why.

For the Royal Australian Mint (or authorised coin producer)

1. Produce coins to the exact standard composition and dimensions listed in Schedule 1, Part 1. The Act is to be treated as if the Schedule includes the listed denominations and standard compositions (s 5(2)(a)-(b)); and each table item in Part 1 “specifies the standard weight, the allowable variation from that standard weight, the design and the dimensions” for the coin (s 6(2)). Use the table entries for nominal weight and allowable variation (e.g. $1 = 9.00 ± 0.66 g; 20c = 11.30 ± 0.78 g; 50c = 15.55 ± 0.96 g) and the maximum diameter/other dimension and thickness figures as manufacturing tolerances (Schedule 1, Part 1 table).

2. Reproduce obverse and reverse designs exactly as described in Schedule 1, Part 2. Obverse O1 and O2 both require an effigy of Queen Elizabeth II and specified inscriptions including “ELIZABETH II”, “AUSTRALIA”, the year and the letters “IRB”; O2 adds numerals for the amount and two dots (Schedule 1, Part 2 items 6-7). Reverse descriptions R1-R5 enumerate precise imagery, inscriptions and in certain items coloured elements; ensure designs match those enumerated elements (Schedule 1, Part 2 items 8-12).

3. Apply composition specifications literally. For example, produce 50c coins with a copper-nickel core and gold plating where specified (Schedule 1, Part 1 item 3). Where the composition is a combination (e.g. copper, aluminium and nickel for $1 coins), ensure material assays confirm the composition meets specification and any relevant internal acceptance testing.

4. Verify shape and edge features. Implement manufacturing processes that yield the correct shape (S1 circular or S2 dodecagonal) and edge treatments (E1 interrupted milling, E2 continuous milling, E3 plain), as those are explicit specifications (Schedule 1, Part 2 items 1-5).

For coin-accepting and coin-handling businesses

1. Update acceptance and detection systems to the specified mechanical parameters. The determination supplies maximum diameter or other dimension, maximum thickness, weight tolerances and edge type for each coin which are the technical parameters for coin validation (Schedule 1, Part 1 table). Adjust sensing thresholds and calibration data to the specified tolerances.

2. Account for plated surfaces and colour in detection logic. The 50c item specifies gold plating and some reverse designs require coloured elements (Schedule 1, Part 1 item 3; Schedule 1, Part 2 items 11-12). Review whether detection systems that rely on electrical conductivity, optical recognition or magnetic signatures will correctly handle plated and coloured coin surfaces.

3. Treat each $1 statutory variant as acceptable. The Schedule contains multiple $1 items with differing reverse designs (Schedule 1, Part 1 items 1, 4 and 5). Ensure machines and cash handling systems are programmed to accept $1 coins that differ in reverse design but otherwise meet the weight/dimension/composition/edge specifications.

For legal compliance and administrative actors

1. Treat the Act as amended for statutory purposes. Section 5(2) requires that the Act have effect as if the Schedule included the denominations and standard compositions in Part 1 of Schedule 1. For legal drafting and compliance purposes, the Act should be read to include those items after the determination commences.

2. Do not assume new enforcement rules. The determination does not set penalties or enforcement procedures; enforcement questions remain subject to the Currency Act and other applicable laws (s 3; see s 5(3) and s 6(4) preserving other determinations). If enforcement or testing procedures are needed, consult the Currency Act and relevant administrative practice.

Practical testing checklist

• Use calibrated precision scales to test weight against the nominal and allowable variation figures in Schedule 1, Part 1.
• Use calipers and appropriate measurement methods for circular and non-circular shapes (note the table heading “Maximum diameter (mm) or other dimension” and S2 dodecagonal shape) to confirm maximum dimension tolerances.
• Confirm edge treatment matches E1-E3 codes in Schedule 1, Part 2.
• Visually inspect obverse and reverse inscriptions and designer initials (e.g. “IRB”, “SD”) to ensure conformity with the textual descriptions.
• For plated coins, conduct surface assays and plating thickness tests to confirm plating meets specification.

Documentation and records

• Maintain manufacturing records demonstrating adherence to the specified standard weight, allowable variation, composition, dimensions, edge treatment, and design elements. The determination itself does not set a recordkeeping standard, but documentary proof will be the mechanism by which compliance with the statutory specification can be shown in administrative or legal contexts.

Dispute and error handling

• Where a coin’s conformity to the statutory description is in doubt due to a manufacturing or design discrepancy, the responsible administrative body (the Mint or Treasury) should compare the physical specimen directly against the Schedule entries (Schedule 1, Part 1 and Part 2) to determine conformity. The determination contains no internal dispute-resolution procedure; resolution will be through administrative correction or general legal remedies if pursued.

Final note

• The determination imposes technical requirements for coin composition, weight tolerances, dimensions, shape, edge and detailed design inscriptions. Compliance is achieved by strict adherence to those textual and numeric specifications in Schedule 1, Part 1 and Part 2 and by treating the Currency Act’s Schedule as if it already contained those items on and after commencement (s 5(2); s 6(2)).
