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. The Sydney Mint and Melbourne Mint no longer operate, making the Perth Mint Australia's oldest currently operating mint.
After the foundation stone was laid in 1896 by Sir John Forrest, the Mint opened on 20 June 1899 as a branch of the Royal Mint in London to refine gold and manufacture gold sovereigns and half sovereigns to be used as currency in the colony.
At that time, Western Australia's population was growing rapidly (23,000 in 1869 and 180,000 in 1900) due largely to the discovery of rich gold deposits in Coolgardie, Kalgoorlie and Murchison areas of the colony.
As there was very little money available in Perth for which miners could exchange gold to pay for goods, the Diggers who flocked to the then colony of Western Australia in huge numbers from other parts of Australia and from around the world, deposited their raw gold at The Perth Mint where it was minted into gold coins.
Between 1899 and 1931, The Perth Mint struck more than 106 million gold sovereigns and nearly 735,000 half-sovereigns for use as currency in Australia and throughout the British Empire. The Mint stopped making gold sovereigns when Britain abandoned the gold standard in 1931. Nevertheless, the refinery remained busy as staff turned their skills to making fine gold bullion bars. But it was not long before the Mint was involved again in the production of coins. During World War II, the Perth Mint began minting the Australian coinage from base metals. Up until the end of 1983, the Perth Mint also manufactured much of Australia's lower-denomination coin currency. The Perth Mint achieved "arguably the purest of all gold" in 1957 when the mint produced a 13-troy-ounce (400 g) proof "plate" of almost six nines - 999.999 parts of gold per thousand. The Royal Mint was so impressed that it ordered some of the gold as the benchmark for its own standards.
The Mint's new direction was formalised in 1987 with the creation of Gold Corporation by a State Act of Parliament. Under a unique agreement with the Commonwealth of Australia's Department of the Treasury, the Mint's new operator was empowered to mint and market gold, silver and platinum Australian legal tender coinage to investors and collectors worldwide. Prime Minister Bob Hawke launches the Australian Nugget Gold Coins Series in 1987. The first day's trading yielded sales of 155,000 ounces of gold worth $103 million, well above the sales target of 130,000 ounces to the end of June. Today, The Perth Mint is a member of an elite group of world mints whose pure gold, silver and platinum legal tender coins are trusted without question. Like the Australian Nugget, its Australian Kookaburra Silver Coin Series and Australian Lunar Gold and Silver Coin Series are extensively sought after by bullion investors worldwide.
Up to 2000, the Mint's refined gold output totalled 4,500 tonnes, representing 3.25% of the total weight of gold produced by humankind. This is about the current holdings of gold bullion in the United States Mint's Fort Knox Bullion Depository.
In 2003, The Perth Mint officially opened an 8,400 square metre state-of-the-art manufacturing facility next door to its original limestone building. Dominating the Mint's heritage precinct, these two important buildings are powerful symbols of more than 100 years of minting excellence in Western Australia.
In October 2011, the Perth Mint created the world's largest, heaviest and most valuable gold coin, breaking the record previously held by the Royal Canadian Mint. The coin is approximately 80 centimetres (31 in) in diameter and 12 centimetres (4.7 in) thick, and made of 1,012 kilograms (2,231 lb) of 99.99% pure gold. It features a red kangaroo on the front of the coin and a portrait of Queen Elizabeth II on the reverse. It is legal tender in Australia with face value A$1 million, but at the time of minting it was valued at A$53.5 million.
Today, the Mint continues to provide refining and other services to the gold industry and manufactures many coin related numismatic items for investors and coin collectors. It is responsible for manufacturing and marketing most of Australia's legal tender precious metal coins, including proof quality Australian Nugget gold coins, Australian Platinum Koala coins, Australian Silver Kookaburra coins and bullion.
