Although athletes really don't go for the gold because of the monetary value, it's nice to know what the medal is made of..and it's worth.

Next week in London, athletes from around the world will go for the gold. But as it turns out, the Olympic gold medal is mostly made of silver. the gold medal is made up of only 1.34%, or about 6 grams of gold. The rest is comprised of 93% silver and 6% copper.

Melted down and sold at today’s market value, those raw materials would be worth about $650.

In comparison, the silver medal — made up of 93% silver and 7% copper —- would be worth about $335. The bronze medal, mostly made of copper, would be worth less than $5.

The Olympic games have not handed out solid gold medals since the 1912 summer games in Stockholm, Sweden.
