Silver Ounce (1 oz), Opal, Coin Type from Australia (issued 2018 - )
Coin TypeSilver Ounce (1 oz), Opal

The Australian one ounce silver piece (abbreviated as 1 oz and designated with Ag for "silver") is a bullion coin format. Uniquely, in Australia there are two mints independently 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.

The Australian Opal series uses a technique pioneered by the Perth Mint in which the reverse design is done with opal inserts instead of being coloured.
