Since the gold rush of the late 1880s, Australia's gold has been refined by The Perth Mint and made into legal tender coins, tradeable bars and exquisite jewellery. Housed in one of the country’s most elegant 19th Century buildings, The Perth Mint is the nation’s oldest operating mint. See a live gold pouring performance in the original Melting House and marvel at the world’s largest gold coin, valued at over $50million.
