I was recently up in Yuba Gap, camping at snowflower, and finding my first geocache. I purchased a little pin at the store there to remember my trip by. Today I put it on my backpack. I thought, hey I wonder if anyone is making signature pins? They look much like the coins, only a cacher can put them on their geocaching pack or other carryall to show off all their finds....I think I will have to look into this, the pin could even fit into a film canister....
