The Perth Mint, owned by the Australian government, is a precious metals mint and refinery, established in 1899, renowned for producing gold, silver, and platinum bullion coins and bars for investors and collectors, as well as the world's largest gold coin in 2011. It was originally created to refine gold from Western Australian gold rushes and mint currency for the British Empire, and today it operates as a government-guaranteed institution with high standards of quality and ethical sourcing.
