The Spyderco SpyderCoin is a custom-minted challenge coin that honors Spyderco’s long standing support for military and law enforcement personnel. This antique-bronze-finished coin has a unique triangle shape and is stamped with the Spyderco logo and the year. They started in 2015 and a new coin was struck each year since. In 2016 the coins were unavailable for purchase and so are harder to find for collectors.
