We think a cachers name on the coin is preferable to not. We have started to mount a collection of coins, but none we have purchased compare to the one we received as a present from a cacher while on a recent excursion. We found a cache with a coin as a present for us inside, complete with the cachers name and unique artwork. To this day we still think that it is the best one in our collection...it keeps it personal. So, our two cents would be to put your name on it and share your uniqueness with the community!
