Olympic Gold Medals are mostly made of Silver!
The difference between winning a gold and silver medal at the Olympics can be a few milliseconds. The difference between a gold and silver medal can be as little as 6 grams! Stipulations require that both medals be made of at least 92.5% pure silver, while the gold medal must be gilded with at least 6 grams of gold! The last time a pure gold medal was awarded in the Olympics was in 1912 in Sweden.
