A geocoin is a trackable coin that is used in the global game of Geocaching (see www.geocaching.com for more details). Geocoins are designed by individuals or groups of geocachers and then minted, often as a kind of signature item and can be highly collectable among geocachers.
Each geocoin is engraved with its own unique tracking code, which allows the coin to be activated and then given a specific goal or mission by the owner. Then the coin is put into a cache and sent to travel the world, and other geocachers use the tracking code to log the coin in and out of caches to record its journey.
Below are the coins I have designed and had minted since May 2010.
