I have kinda been getting in to some of the state quarter error coins lately. I found this link on ebay, and for the life of me, I don't see the "bridge climber" he is talking about...does anyone else? West Virginia Error Quarter?
As described, it's a die chip on the third bridge support from the left. It is just a raised blob in the center of the support. If you take a sip of Jack Daniels and squint hard it's not hard to make it out. The die break on the initials is interesting.
