I've found a few cache cards in my time geocaching. These signature swag items left by fellow geocachers usually have a photo of the geocacher and perhaps some bits of their geocaching history. In my recent travels, I found a cache card that had a discoverable tracking number on it (discoverable at geocaching.com/track). Fun! This inspired me to make my own caching card, but with a crafty TXGeekette spin. Instead of a typical cache card, I decided to make a series of Artist Trading Cards (ATCs) with the discoverable tracking number for one of the geocoins I have that I won't be putting into circulation.
I'll be making a total of 100 (A series of 10 with 10 editions) cards with the discoverable trackable number from this geocoin:
