Challenge Coins are a military tradition, which is said to originate at the start of last century. They were distributed based on merit in events or for other reasons, and hold deep personal value.

To find out more about Challenge Coins, you can listen to the 99% Invisible podcast about them, or read up about them on Wikipedia.

The BeeWare Challenge Coins are die cast, 4.5cm (1 3/4") in diameter, and are made of a nickel/zinc alloy with enamel highlights.

Any contribution to the BeeWare project earns you a coin.

It doesn't have to be a code contribution: a documentation update counts. A blog post. Helping someone during a sprint with their contribution.

And as an additional incentive, for those people who help others get their challenge coins, we have a second coin: the Yak Herder
