Ok, I found this penny today, and it looks like the "D" mintmark is filled in. I do not believe a filled Die could cause this, because it would result in a weak looking or non existant feature rather than a filled in "D". Could someone please help me figure out if this is an error during the minting or if this is after mint damage. Thank you in advance for your help. Kyle
The "hole" that is supposed to be in the center of the "D" is made by a corresponding high spot on the die. That high spot has broken off of the die used to strike your coin. I don't think there is any premium value to your coin. Have you looked at the Coneca web site?
