CoinTwenty Cents 2009 Decimal Pattern

In May 2009, the Perth mint released a proof coin set based on Andor Mészáros 1966 decimal currency designs.

The tribute set contains five coins which reproduce the reverse designs submitted by Andor Mészáros for the low-denomination coins, 20, 10, 5, 2 and 1 cent, in Australia's first issue of decimal currency in 1966. The obverse of the coins was designed by Ian Rank-Broadley. The coins in this set are proof quality silver. They were created using plasters supplied by the Mészáros family.

Mészáros was a prominent sculptor and medal artist based in Melbourne. As part of the project to introduce decimal currency to Australia, the Advisory Panel on Coin Design commissioned six artists, including Mészáros, to submit reverse designs for the new coins. Andor's designs included Australian flora (wattle and waratah) and fauna (platypus, yabbie, kookaburra, snake and black swan). The successful artist was Stuart Devlin, a Geelong-born gold and silversmith, later based in England.

This set highlights the artistic endeavours involved in the development of decimal currency, which was a major event in Australia's numismatic history.

Mass: 12.86 g. Diameter: 28.6 mm. Composition: 0.999 silver (0.413 oz. ASW).

Obverse

Crowned mature head of Queen Elizabeth II facing right (effigy known as the "Fourth Portrait"). The Queen wears the "Girls of Great Britain and Ireland" diamond tiara, a wedding gift from Queen Mary (Her Majesty's grandmother) in 1947 - which she also has on the Machin and the Gottwald portraits.

In tiny letters below the head, the artist's initials IRB (for Ian Rank-Broadley).

Around the effigy is the monarch's legend and the date: ELIZABETH II AUSTRALIA 2009.

The effigy of the Queen is smaller than on regular coins.
