Found this a little while ago, did some research, and came to this hypothesis: this 1980 LMC was struck through the thinnest of die caps. It looks really similar to the one on the far right on error-ref.com. Check out the link below. Also, I'm not selling this because it will be the first of this error type I have found, but do you guys have any idea of value? If it is what I think it is anyway! Thanks all! http://error-ref.com/Struck_through_a_late_stage_die_cap.html
Hello Jay , I have a coin here somewhere in my collection that looks similar to yours , it may be from the same capped die. mine is in poor condition from being used too much
