I've been researching this penny for nearly 2 and a half years. I'm still not able to get a difintive solid explaination. Here is what I know. It isn't a delamination bubble. It can't be depressed with a tooth pick. The pictures I have aren't the best so I'll tell you that the dashed area is a raised, beveled surface that matches uniformly with the lettering. In all of my searches for campaign or commerative coins, this coin doesn't show up. I haven't had it xrayed because I don't know if spending the money on it would be worth it's future value if it's proven to be a mint error. Suggestion? Ideas? Explainations will be taken into consideration. Thanks in advance. Look at my profile for pictures of the penny.
sounds like plating blister, Zincolns are known for all kinds of plating issues..http://www.error-ref.com/?s=plating
