The Australian one-ounce gold piece (abbreviated as 1 oz and designated with Au for "gold") is a bullion coin format. Uniquely, in Australia there are two mints authorised to strike legal tender: the Royal Australian Mint (which also makes the country's circulating coinage) and the Perth Mint which only makes collector and bullion coins, as well as other bullion products.
Both mints endeavour to create coins with attractive designs, and to introduce new designs and themes often, in order to raise the numismatic value of the coins over the value of previous metal used.
This coin is part of the long-running Australian Kangaroo bullion coin series by the Perth Mint.
The mint says about it:
A prestigious gold bullion coin series with a tradition dating back to the 1980s, the annual Australian Kangaroo includes a popular 1oz coin which in 2024 features an exceptional design that investors will eye as a new classic.
The kangaroo is synonymous with Australia. Millions inhabit this wide brown land, from the arid interior to bushland, parks and other open spaces fringing our cities. With a superb new artistic impression each year, the Australian Kangaroo Gold Bullion Coin Series celebrates Australia’s most famous marsupial.
Struck on a thicker blank, high relief coins portray a plumped up design, which on this remarkable piece is a large kangaroo about to leap over a parched creek bed. |
