One Dollar 2018 Sir John Monash, Coin from Australia - detailed information

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 non-circulating coin commemorates Sir John Monash.

The mint says about it:
Sir John Monash (1865 - 1931) is one of the greatest figures in Australian history. An outstanding commander during the First World War, he continued his exceptional service upon his return and was knighted for his services in 1918. His postwar endeavours both served the community and helped build the nation we are privileged to enjoy today. Military enthusiasts, proud Australians and collectors will all value the story of one of Australia's greatest figures, told with these unique coins.
