Did you know an Olympic medal is not worth so much cash, but glory and fame. The 500-gram gold medals earned by Usain Bolt, Michael Phelps and Simone Biles are nearly 99 percent recycled silver. They contain just 1.2 percent gold, mostly used as plating, Daily Mail reports.
They are worth about $587 in current market prices. Victor Hugo Berbert, head of medal-making at Brazil's National Mint in Rio de Janeiro, said:
It's a great honor and a great responsibility,' Each of the 5,130 Olympic and Paralympic medals took about 48 hours to make.
Much of the silver is recycled from old mirrors and X-ray plates. The gold is free of mercury, which is often used to separate gold from ore and can poison local ecosystems if not carefully disposed of.
The last time athletes earned medals made of pure gold was at the 1912 Olympics in Stockholm, Sweden.
