Silver Ounce 2020 Spinner Dolphin, High Relief, Coin from Australia - detailed information

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.

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 Spinner Dolphin one-ounce silver bullion coin is the second dolphin-themed coin by the Royal Australian Mint after the Bottlenose Dolphin issue of 2019. This is a special version of the silver ounce, with high-relief surfaces; it has face value of $5 to distinguish it from the other one-ounce coins. Given that it has the same mass but bigger thickness, the diameter of the coin is smaller.

The spinner dolphin (Stenella longirostris) is a small dolphin found in off-shore tropical waters around the world. It is famous for its acrobatic displays in which it spins along its longitudinal axis as it leaps through the air. It is a member of the family Delphinidae of toothed whales.

The coins are in Proof grade and were made available exclusively through APMEX, boxed and with a numbered Certificate of Authenticity.
