What it does
This instrument, the Currency (Perth Mint) Determination 2001 (No. 4), is a ministerial (executive) specification instrument made under subsection 13A(1) of the Currency Act 1965, signed by the Parliamentary Secretary to the Treasurer, Ian Gordon Campbell, and dated 19 December 2001. The Determination commences on gazettal (cl 2). Its operative function is limited and technical: it prescribes the physical and observable specifications for a set of Perth Mint coins listed in Schedule 1, Part 1, including denomination, metal fineness (standard composition), standard weight with allowable variation (in grams), diameter and thickness (in millimetres), shape and edge treatment, and the obverse and reverse design elements (cl 3 and Schedule 1, Part 1).
The Determination does not itself create offences, authorise minting in a procedural sense, or state broader legal effects such as legal tender status or customs treatment. Clause 4 expressly provides that the specifications in this Determination do not affect any other Determination of the specifications of a coin. The Schedule maps shorthand symbols (for shape, edge, obverse and reverse) to full design descriptions in Part 2, including precise inscriptions, effigy content and privy-mark features. Several reverse designs include material exceptions to the standard composition for the privy mark (for example, a pure gold or pure silver insert), which the Schedule records parenthetically in the composition column for particular items (see items 101, 102, 106 and 107).
Mechanically, the Determination instructs what manufactured coins must look like and weigh, to the tolerances stated. It provides the design blueprint for a 2002 series of Perth Mint bullion or numismatic coins (the reverse inscriptions include the year '2002'), specifying both bullion-type metal fineness (99.9% silver; 99.99% gold) and small absolute weight tolerances (for example ±0.500 g for 2 oz silver coins, and ±0.055 g for the 1 oz 99.99% gold coin). The document is a self-contained table of specifications; it does not set out minting process rules, approval workflows, or enforcement provisions.
