What it does
This Determination, styled the Currency (Royal Australian Mint) Determination 2004 (No. 4), is a specification instrument made under subsections 13(2) and 13A(1) of the Currency Act 1965 (the Determination). It is signed and dated by ROSS CAMERON, Parliamentary Secretary to the Treasurer, as of 9 June 2004, and takes effect on the date of its notification in the Gazette (clauses 1 and 2). Mechanically, the instrument performs two functions.
First, clause 3 records that, for the purpose of the two cited subsections of the Currency Act, each item in Schedule 1 specifies core technical and design attributes of individual coins. The text of clause 3 lists the attributes that each Schedule item specifies: denomination; standard composition; standard weight and allowable variation; dimensions; and design. Those are the specific legalised characteristics the Determination records against each item in Schedule 1.
Second, clause 4 preserves the status of other specification determinations by stating that the specifications in Schedule 1 do not affect any other determination of the specifications of a coin. That is, the Determination is additive or parallel to prior or subsequent determinations and does not withdraw or supersede other specification determinations by implication.
Schedule 1 is the operative annex. It contains eight distinct items, each labelled with an item number and a short heading (for example, "Item 1 , $1 coin"). Each item sets out the listed attributes in tabular form. The items specify multiple $1 coins with differing compositions, weights, shapes and designs (Items 1-6), and two higher-denomination coins, $150 and $200, composed of high-purity gold (Items 7-8). The specified metal purities include "at least 99.9% silver" for the $1 items and at least 99.99% gold for the $150 coin; Item 8 specifies "at least 99.9% gold" for the $200 coin. The Schedule also sets maximum diameters and thicknesses, edge types (plain, milled, segmented), shapes (heptagon, scalloped, circular), obverse and reverse design elements and inscriptions (for example, the obverse design across items includes an effigy of Queen Elizabeth II and the monogram "IRB" with specific inscriptions; reverse designs vary). The Schedule therefore produces legal, enumerated technical descriptions for a set of Australian coins.
