Platinum Ten Ounces 1991 Australian Koala, Coin from Australia
CoinPlatinum Ten Ounces 1991 Australian Koala

The Australian ten-ounce platinum piece (abbreviated as 10oz and designated with Pt for "Platinum") is a very large 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 is the first coin in the Australian Koala series in this size.
