Tak: A Beautiful Game - Collector Coin
This Collector Coin is 36 mm square (approx. 42 mm on the diagonal) and is ideal as a centerpiece marker, allowing you to play Tak without a board! (Please note that the Collector Coin does not come with any game pieces.)
Additionally, the coin is pierced in one corner, so you can add a jump ring and turn it into a fine-looking pendant or keychain.
Like all of Cheapass Games' previous collector coins, this one will be produced by the fine folks at Campaign Coins.
