What are Pathtags?
A pathtag is a small (1" diameter) coin that is left as signature items by some geocachers. The design on the face of the coin is customized, while the other side holds a generic design and a serial number. Pathtags are usually meant to be kept by the finder, instead of being moved like activated geocoins. They are very popular for trading at events and on the pathtags.com website.
