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.
The 2020 Sumatran Tiger one-ounce gold bullion coin is the first release in a new Australia Zoo coin series and features a Sumatran tiger.
He belongs to the critically endangered species - the number of tigers living in the wild is estimated at fewer than 400 worldwide. The rare species is the smallest living subspecies of the tiger and has its habitat exclusively on the island of Sumatra (Indonesia). Beside his smaller body size, the Sumatran tiger also differs from other tigers by his very strong fur base colour. |
