Australia’s Perth Mint has over a century of experience refining gold, silver, and other precious metals. It is a world leader in fine gold, creating the world’s largest, heaviest, and most valuable coin, which broke the record previously held by the Royal Canadian Mint. The 31 inch diameter and 4.7 inch thick coin was made from 1,012 kilograms of 99.99% pure gold, and featured the classic gold nugget Kangaroo design. It has a face value of 1 million dollars. At the time of minting, this Australian Gold Nugget was valued at $53.5 million AUD!
