I've been reading about the Wisconsin quarter error and I have to say I'm a bit skeptical of the claimed values of some of these coins. While I do think it's possible to find some rare errors in circulation, I'm not convinced that some of the prices people are throwing around are realistic. I'd love to see some more expert opinions on this topic and hear from people who have actually purchased and sold these coins.
