An Olympic gold medal is almost 99% silver.

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. And approximately how much are all these precious medals worth, you ask? The gold - $494, the silver - $260, and the bronze...$3!
