JoelMart is a Pennsylvannia geocacher who has been playing the game since the beginning. His first geocache find was on September 30, 2001, and he has been geocaching steadily up to now (December 2012). This large, 4 mm thick personal geocoin was issued in late 2005, so it is from the early days of geocoins. I believe that there were 200 non-trackable geocoins minted, and 50 trackable. Not sure where I got it, but I'm happy to have it in my collection. The geocoin tells us "Don't fear the muggles" but I have to admit to being slightly skittish when it comes to geomuggles.
