Gold Quarter Ounce 2012 Diamond Jubilee, Coin from Australia - detailed information

The Australian quarter-ounce gold piece (abbreviated as 1/4 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.

This commemorative gold proof coin was issued to celebrate the Diamond Jubilee (60th anniversary of the accession to the throne) of Queen Elizabeth II.

The mint says about it:
Her Majesty ascended the throne on 6 February 1952 and was crowned Queen Elizabeth II on 2 June 1953 at the age of 27. Her Majesty The Queen has been witness to many astonishing changes that have taken place in the world, from the Second World War to the landing on the moon. During the sixty years of her reign she has also seen radical developments in the areas of medicine, transport and technology. In addition, Her Majesty has faced many personal challenges with courage, strength and dignity - qualities for which she has become renowned.
