Step 1: Use the Determination as the authoritative specification. For any coin production matching the denomination and standard composition entries in Schedule 1 Part 1, the producer must implement the date, weights, dimensions and designs as specified (s 3; Schedule 1 Part 1). Start by mapping each coin type (items 101-110) to the detailed explanation in Schedule 1 Part 2 to ascertain exact obverse and reverse requirements.
Step 2: Material procurement and assay. For coins requiring minimum precious-metal purities, procure materials demonstrably meeting the stated specifications. Examples: item 101 centre piece "at least 99.9% gold", item 102 "At least 99.9% silver", and item 110 "centre piece , at least 99.99% silver, with a gold plated insert composed of 99.9% gold" (Schedule 1 Part 1). Maintain supplier documentation, assay certificates and chain-of-custody records to evidence compliance. For base-metal alloys that are specified by components without percentages (e.g. “Copper, zinc, aluminium and tin”), document the alloy composition produced and, where policy or practice requires consistency, set an internal standard composition to ensure repeatability.
Step 3: Manufacturing tolerances and quality control. Implement production controls to meet the listed standard weights and allowable variations (e.g. 36.31 ± 0.64 g). Calibrate scales and measurement environments. Establish inspection sampling plans that reliably detect out-of-tolerance pieces. For multi-component coins and plated inserts, design assembly and bonding processes that do not affect the final weight beyond allowable tolerances.
Step 4: Die and design production. Translate the symbol codes into die specifications using Schedule 1 Part 2. For obverse O27-O31 and reverse R292-R301, prepare dies, inserts and pad-printing tooling capable of reproducing inscriptions and motifs precisely, including any colour requirements (R296 pad-printed in blue) and any gold-plated inserts bearing inscriptions (O31 and R301). Ensure the monogram ‘IRB’ and the effigy of Queen Elizabeth II are reproduced as described in the relevant obverse codes.
Step 5: Special process controls. For gold plating and pad-printing, control plating thickness, adhesion and plating purity to ensure the insert meets the “99.9% gold” composition requirement where applicable. For pad-printing, validate colour consistency and adhesion to the coin surface using accelerated wear testing, even though the Determination does not specify durability standards. Retain test records.
Step 6: Documentation and traceability. Maintain manufacturing records that show coin-by-coin or batch compliance with weight, diameter, thickness, composition, and design requirements. If third-party assays are used, retain certificates. If subsequent audits arise under the Currency Act or other regulatory oversight, complete documentation will demonstrate compliance with Schedule 1.
Step 7: Cross-reference other determinations. Section 4 preserves other determinations. Before asserting compliance for a particular coin type, confirm there are no other determinations that also apply to the same denomination or design and reconcile any differences. Maintain a register of applicable determinations and their effective dates.
Step 8: Stakeholder communication. If coins are to be issued commercially, coordinate with distribution partners and banks to communicate unusual dimensions, weights or non-standard features that might affect handling or acceptance. Provide specification sheets referencing the Determination (Schedule 1 Part 1 and Part 2) for downstream operators and assayers.
Step 9: Legal and IP clearance. Although the Determination prescribes the use of specific imagery, confirm any parallel legal requirements relating to the use of the effigy, monograms, or association logos, especially when third-party logos are reproduced (for example the Australian Commonwealth Games Association team logo in R296). The Determination specifies the logo must be “pad-printed in blue”, but other permissions or agreements may be required for use.
Step 10: Ongoing review and amendment monitoring. Because the Determination does not carry amendment history in its text, maintain a regulatory watch on the Currency Act delegated instruments and the Register of Instruments to capture any later modifications or supersessions. Also monitor for technical guidance from the Treasury or the Mint that clarifies measurement protocols or production expectations.
Following these steps aligns operations with the Determination’s explicit requirements: composition, weight and allowable variation, dimensions, shape and edge, and specific obverse and reverse designs as mapped in Schedule 1 Part 1 and Part 2, and it respects section 4’s preservation of other determinations.
