Why do Olympians bite into gold medals?

And what are the medals actually made from? Spoiler: mostly not gold.

Weighing between 500g and 800g, gold medals are actually made from silver coated with at least 6g of pure gold. A ‘gold’ medal’s value depends on global markets, but those issued in Rio in 2016 were estimated to be worth over £360 each.

Medals for the delayed 2020 Tokyo Olympics are made from recycled metals. The host country’s mint is responsible for making medals, following International Olympic Committee specifications. Solid gold medals haven’t been handed out since 1912.
