The gold coin "Big Maple Leaf" was on display at Berlin's Bode Museum. The Big Maple Leaf weighs 100 kg and measures 53cm across, and is thought to be the world's biggest coin. The coin has a face value of $1m, but the gold in it makes it worth almost $4.5m at today's market prices. The museum says the Big Maple Leaf is in the Guinness Book of Records for its purity of 999.99/1000 gold. It has a portrait of the Queen on one side and maple leaves on the other. Berlin police said it was taken by thieves who broke into the Bode museum in the city at around 3.30am on Monday. (Photo/Agencies)
