The world’s biggest gold coin was auctioned in Vienna, Austria on 25 June, 2010. The gold coin, which weighs 100 kilograms, fetched over $4 million, which was shelled out by a Spanish precious metals trading company. The gold coin is one of only five Canadian $1,000,000 Maple Leaf coins by the Royal Canadian Mint.
The auction was held by an Austrian investment group AvW Invest, who went bankrupt after a series of fraud by its owner and chief executive.
