I read from some sources that the dream of every sportsman, the Olympic Gold Medal, is not 100% pure gold. (Olympic Gold medals are required to be made from at least 92.5% silver, and must contain a minimum of 6 grams of gold).
The last series of Olympic medals to be made of solid gold were awarded at the 1912 Olympic Games in Stockholm, Sweden.
Do any of the present sports competitions give pure solid gold medals for the winners?
