Thank you for clarifying this Cliff. Also the same thing about mint mark location applies to RPM's up to and including 1989. Since I was referring to doubled dies (and I forgot to mention RPM's)... and you are referring to Die Varieties, here is the definition of a Die Variety.

Die Variety: An abnormal coin struck from a die that had a mistake made during the transfer of its design onto the die. Die varieties include doubled dies, re-punched and misplaced mint marks, over mint marks, dual mint marks, and re-punched and misplaced dates. (The practice of punching the date into the die stopped before the Lincoln Cent series began, so there are no re-punched or misplaced dates on Lincoln cents) These are NOT considered “errors.”
