What it does
This Determination, titled Currency (Royal Australian Mint) Determination 2013 (No. 3) (s 1), is a statutory instrument made under the Currency Act 1965. It prescribes, for a list of coin items in Part 1 of the Determination, the mechanical specifications that determine a coin’s standard weight, the allowable weight variation, the coin’s dimensions and the coin’s design, expressly for the purposes of subsection 13A(1) of the Act (s 4(1)). The Determination therefore sets out binding technical characteristics for multiple coins, including a number of $1 coins, some higher face‑value gold coins and bullion/commemorative silver coins, by linking each item in Part 1 to four concrete data points: (a) standard weight; (b) allowable variation; (c) dimensions; and (d) design (s 4(1)(a)-(d)).
Mechanically, the instrument operates by enumerating coin items in Part 1 (a tabular schedule) and by cross‑referencing codes for shape, edge, obverse and reverse designs that are explained in Part 2. Part 1 rows state denomination, standard composition, numeric weight and allowable variation (for example "10.03 ± 0.50" grams), numeric diameter and thickness values, and symbolic codes for shape, edge, obverse and reverse. Part 2 decodes those symbolic codes into text descriptions (for example S1 means circular, E1 interrupted milling, O1 an effigy of Queen Elizabeth II with specified inscriptions, and a long list of R codes describing reverse designs).
Section 5 limits the Determination’s effect by stating that section 4 does not affect any other determination of standard weight, allowable variation, dimension or design of a coin made under subsection 13A(1) of the Act. In practical terms, the Determination is a particular exercise of rule‑making power under the Act that coexists with other such determinations, and it becomes operative “on and after the day on which this Determination commences” for the listed items (s 4(1)).
