Gold Ounce 2017 Australian Kangaroo, High Relief, Coin from Australia - detailed information

The Australian one-ounce gold piece (abbreviated as 1 oz and designated with Au for "gold") is a 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 Australian Kangaroo 2017 1oz Gold Proof High Relief Coin is part of a long-running series by the Perth Mint, which features a new depiction of the Australian national animal every year. It has smaller diameter than the bullion ounce, and is struck on a thicker planchet.

The mint says about it:
Featuring the 2017 kangaroo design, this coin is meticulously struck in brilliant high relief, showcasing the very best in minting excellence. The coin's reverse depicts a kangaroo bounding across an outback plain. The coin’s high relief reverse and obverse are minted on concave surfaces to ensure the optimum flow of metal is achieved by the strike of the die.

Issued as legal tender under the Australian Currency Act 1965, the coin's obverse depicts the Ian Rank-Broadley effigy of Her Majesty Queen Elizabeth II and the monetary denomination.
