Overview

The Currency (Perth Mint) Determination 2004 (No. 3) was enacted to specify the standards and specifications of coins produced by the Perth Mint under the Currency Act 1965. This legislation addresses the need for precise standards and specifications for currency coins to ensure consistency, quality, and legal tender status. The Currency Act 1965 empowers the Treasurer to make such determinations, and this particular Determination was made under subsection 13A(1) of that Act. The primary policy objective is to maintain the integrity and quality of Australian currency by clearly defining the standards for coin production. The Determination sets out the specifications for various coins, including their denomination, composition, weight, dimensions, and designs, ensuring that they meet the legal requirements for use as currency in Australia.

Scope and Application

The Currency (Perth Mint) Determination 2004 (No. 3) is a legislative instrument made under the Currency Act 1965, which governs the minting and specifications of Australian currency. This Determination, as amended, applies to the specifications of particular coins minted by the Perth Mint, including their composition, weight, dimensions, and design. It specifically details the specifications for one dollar coins with various reverse designs, as well as a twenty-five dollar coin. The Determination is binding and applies from the date of its notification in the Gazette. Notably, it does not affect any other determinations regarding coin specifications. The scope of the Determination is limited to the coins specified in the Schedule and does not extend to other forms of currency or coins minted elsewhere. The Determination is subject to amendment through subordinate instruments, as evidenced by the Currency (Perth Mint) Determination 2004 (No. 3) Amendment Determination 2005 (No. 1), which amended the original Determination.

Key Provisions

The Currency (Perth Mint) Determination 2004 (No. 3) (sections 3 and 4) sets out specific specifications for certain coins minted by the Perth Mint, including their denomination, standard composition, weight, dimensions, and design. For instance, the $1 coins must be at least 99.9% silver, weigh 31.635g with a variation of ± 0.500g, and have a maximum diameter of 40.60mm and thickness of 4.00mm. The designs, both obverse and reverse, are also meticulously detailed, featuring inscriptions such as "ELIZABETH II" and "AUSTRALIA," an effigy of Queen Elizabeth II, and various representations of zodiac symbols. The $25 coin, specified in Item 13, must be at least 91.67% gold and 8.33% silver, with a weight of 8.001g ± 0.013g, and a diameter and thickness of 22.15mm and 1.90mm respectively. Under this Determination, the Perth Mint is obligated to ensure that all minted coins adhere strictly to the specifications provided in Schedule 1. This includes the use of the correct materials, precise weight, dimensions, and design elements as detailed. Any deviation from these specifications could result in non-compliance with the Currency Act 1965 and potentially render the coins unacceptable as legal tender. The Currency Act 1965 does not explicitly outline offences, penalties, or consequences for breaches of the Determination. However, failure to comply with the specifications could result in the coins not being recognized as legal tender, leading to potential financial and legal ramifications for both the mint and those who use or trade these coins. Furthermore, any deliberate or negligent deviation might attract scrutiny under other relevant legislation concerning the production and distribution of currency.
