Olympic golds?

The Olympic Games last awarded solid gold medals at the 1912 Summer Games in Stockholm, Sweden, when gold was valued at around $20 an ounce — a fraction of today’s price.

This year’s gold medals are 92.5 percent silver, 1.34 percent gold and the remainder copper. The 2012 silver medal is 92.5 percent silver and the rest copper, while the bronze medal is 97 percent copper, 2.5 percent zinc and 0.5 percent tin.

The British Royal Mint made the 2,300 Olympic medals from almost nine tonnes of metal from two Rio Tinto mines.
