Coin rolling machine damage, it was on the end of the roll when it was crimped. Worth ten cents. Also looks like it was struck through grease around the oak leaves.
Thank you, so this would be an example of grease possibly? This is a 1969 d, and from what I'd guess is that it is not "missing" the initials, they just never got fully stamped? Just guessing, I'm very new to this all.
