What are they worth?
According to the Olympic Charter, the gold and silver medals must each be made of at least 92.5 percent pure silver and the gold medal must be gilded with at least six grams of gold. The first-place medal is actually 550 grams of silver covered with a thin layer of gold (6 grams)! A silver medal is far more authentic - 509 grams of silver and 41 grams of copper. The bronze medal is composed of mostly copper, with some zinc and tin mixed in. One can ask with the gold prices changing on daily basis approximately how much are all these precious metals worth.
