This personal coin issued by Anthus -- a geocaching family from Pennsylvannia -- is actually a decoder geocoin! Kind of like the decoder rings we used to get in cereal boxes, except much nicer. This decoder coin can aid geocachers who possess it in finding the Anthus Decoder multi-cache. This geocoin ranks as one of the more unique pieces out there (in my limited experience).
