That looks like it could flake off? Do you think a piece of copper fell on the planchet just before it was struck? hmmmm.....
Looks like a "Lamination error" check this link- http://www.lincolncentresource.com/Errors/Laminations.html Hope this helps, and by the way, nice find. Bill :smile
It's actually a coin where a thin layer was splitting away from the planchet when it struck. The strike folded over the thin layer and struck it into the coin. I'm sure there's a specific name for the error, but I don't know what that name would be right off. I can say that it is significant and would be worth a premium value. Don't ask, I don't know.
Could it be a lamination-folded over before strike. Mike Diamond is discusing one here now http://groups.yahoo.com/group/errorcoininformationexchange/
It is so nice to have good members like Chuck and Mike to help us with our error and variety coins. Most people would have shrugged that one off as just a regular lamination and nothing more. I would get that baby in an anacs holder. Could bring a little $$$ your way. Tom
Nice find, and better still nice pictures to review. To me, it looks like an added piece of metal got caught between the planchet and the die. I can't tell what that little gob of material is on the right side, but it might be part of that extra metal, an unusually large piece. My comments are based on a conversation about this type of find while at the ANA conference in Milwaukee 2 years ago. An attendee had two dimes that were compressed into one, I did not get to see it, but there was an informal discussion about finding "extra metal" on coins. Please let me know if you get other replies with different explanations, I'm as new at this as a 2005 cent.
