Thank you for the warm welcome. For that first 2005D coin there's no glue. That raised area with the reverse lettering is copper. So I guess a piece of a penny chipped off on the die and it got struck on to the next penny? Is this coin worth anything?
Thanks for identifying the counter stamp on that coin.I'm thinking this coin actually had glue on the reverse. If its not worth anything because of the condition I 'll just keep it.
