Head here...http://www.pcgs.com/prices/...for some reason I can't get mine to open right now.creeper71 said:yeah it is smooth.. I thought someone damaged it that is why I put possible error.. I don't know much about coins an knew you guys would help me determine if it was a error or not.. lil more disappointing is it is a 1983 no mint mark quarter... anyone know why a 1983 quarter is worth 2.30?
