Weighing in at 100 kilograms (220 pounds) and bigger than a large pizza, this gold coin, the biggest in the world, went on auction in Vienna and was sold for a whopping $4 million.

The Maple Leaf coin has an image of Queen Elizabeth II on one side and was minted in Canada in 2007. Face value of the pure gold coin is one million Canadian dollars.

However, it fetched four times as much at the auction. That would have been an excellent investment.

Bet you this is one coin you can’t flip. Not without a crane anyway. Via Gillian Young
