Platinum Kilo (1 kg), Coin Type from Australia - detailed information

The Australian one kilogram (1kg) platinum piece 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.

The overall weight of the coins is slightly over a kilo, so as (accounting for the purity of the alloy) to have exactly 1,000 grams of platinum content.
