The Australian one-dollar coin is the second most valuable circulation denomination coin of the Australian dollar after the two-dollar coin; there are also non-circulating legal-tender coins of higher denominations (five-, ten-, and two-hundred-dollar coins[3]).
It was first issued on 14 May 1984[4] to replace the one-dollar note which was then in circulation, although plans to introduce a dollar coin had existed since the mid-1970s. The first year of minting saw 186.3 million of the coins produced at the Royal Australian Mint in Canberra.[4]
Four portraits of Queen Elizabeth II have featured on the obverse, the 1984 head of Queen Elizabeth II by Arnold Machin; between 1985 and 1998, the head by Raphael Maklouf; between 1999 and 2009, the head by Ian Rank-Broadley; and since 2019, the effigy of Elizabeth II by artist Jody Clark has been released into circulation. The coin features an inscription on its obverse of AUSTRALIA on the right-hand side and ELIZABETH II on the left-hand side. One-dollar coins bearing the portrait of King Charles III entered circulation in December 2023.[1]
The reverse features five kangaroos. The image was designed by Stuart Devlin, who designed Australia's first decimal coins in 1966.
The one-dollar denomination was only issued in coin sets in 1987, 1989, 1990, 1991, 1992, and finally 2012. No one-dollar coin with any mint mark was ever released for circulation; any dollars found with such mark comes for a card.
$1 coins are legal tender for amounts not exceeding 10 times the face value of the coin for any payment of a debt.[5]
See main article: article and Commemorative coins of Australia. The Royal Australian Mint has released a number of commemorative issued coins since the Australian $1 was released in 1984, some of which were not released into circulation.
