Information about mint: Perth Mint

The Perth Mint played a central role in the development of Western Australia's gold industry. During the 19th century, three branches of the Royal Mint of London were established in the Australian colonies to refine gold from the gold rushes and to mint gold sovereigns and half-sovereigns for the British Empire. The Sydney branch opened in 1855, the Melbourne branch in 1872 and the Perth branch on 20 June 1899, two years before Australia's Federation in 1901.

After World War I the production of sovereigns for circulation by the Royal Mint ceased; branch mints ceased production as their need for the coin diminished. Sydney was closed in 1926 but Melbourne went on striking until 1931 and Pretoria until 1932. Melbourne and Perth continued as branch mints, their main work being the treatment of gold and production of gold bars with contracts from the Australian Government to strike local coins. Royal Proclamations dated 29 May 1970 officially ended the role of Branches of the Royal Mint for Melbourne and Perth mints on 1 July 1970.

The Sydney Mint and Melbourne Mint no longer operate, making the Perth Mint Australia's oldest currently operating mint.
