The one dollar coin circulating denomination (written as $1) was introduced in Australia in 1984, replacing the earlier banknotes. The original reverse design by Stuart Devlin featuring five kangaroos - known in Australia as the "Mob of Roos" design - has not been changed since its introduction.
The denomination is also used by both the Royal Australian Mint and the Perth Mint to issue an extensive range of collector coins, which are legal tender in Australia - such as this one.
This coin is part of a seven-coin series by the Royal Australian Mint marking the participation of Australia in the Commonwealth Games held in Birmingham (United Kingdom) from 28 July to 8 August 2022.
The Mint says about it:
"Celebrate everything Australia loves about sport with this vibrant collection of coins honouring the 2022 Australian Commonwealth Games Team. Representing Australia in 21 exhilarating sports including 8 Para-sorts, across 24 disciplines, the team comprises some 400 of the nation’s most talented and determined athletes. As a country that lives and breathes sport, it’s no wonder that Australia is one of only six countries to have competed in every Commonwealth Games since their inception in 1930. Capture the spirit of the green and gold with this exquisite seven-coin collection."
The four one-dollar coins in the series represent various qualities important to the games: integrity, respect, excellence and inclusiveness. The mint doesn't credit a specific person for the design, but lists "Royal Australian Mint" as reverse designer.
