The largest gold coin in the world — measuring 53 cm in diameter and weighing 100 kg — will go on sale on June 25 in Vienna, auction house Dorotheum said on Friday.

The Maple Leaf coin, which is listed in the Guinness Book and carries a face value of one million Canadian dollars (U.S. $970,000), was minted in Canada in 2007.

The auction price is expected to comfortably exceed the face value due to the current high price of gold. If melted down, the gold would be worth around $ 3.9 million.

One side of the coin carries the carries the image of Queen Elizabeth II, the official head of the State of Canada, while the other side bears three maple leafs, the national symbol.

The coin was owned by Austrian investment firm AvW, which entered bankruptcy proceedings in May.
