One Tonne gold coin on display at The Perth Mint in The Perth Mint Gold Tour.

World’s largest gold coin

The one tonne gold coin at The Perth Mint is a major drawcard

Inspired by the enduring popularity of the annual Australian Kangaroo Gold Bullion Coin Series, this mammoth coin has been a visitor highlight since it was cast in 2011.

The gold coin tips the scales at a massive one tonne of 99.99% pure gold. 

Measuring about 80 centimetres wide and 12 centimetres deep it is the biggest, heaviest and most valuable gold bullion coin in the world.
