The Australian one ounce silver piece (abbreviated as 1 oz and designated with Ag for "silver") is a bullion and commemorative 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.
Some of these coins can be classified as "Smartminting" (or "smart minting") due to the technologies used in their production; these include irregular shapes, coloured surfaces, precious stone inserts etc. The coins are targeted at collectors who appreciated them as art rather than at bullion investors. |
