IMO it has possibilities. There's only 2 listed here:http://varietyvista.com/02b LC RPMs Vol 2/RPMs 1980D.htm Wexler lists 11 but no photos: http://doubleddie.com/1711174.html Ask the error experts @Fred Weinberg; @paddyman98; @furryfrog02; @JCro57; @desertgem; @cpm9ball; et al.
I'm not a big fan of Lincoln cents because they give me headaches, but it doesn't look like an RPM to me. It looks like a combination of machine doubling and die deterioration. @Rick Stachowski is the resident aficionado on Lincoln cents varieties. Chris
No expert here, but if it were MD, wouldn't there be at least a hint of it in the nearby date? I thought MD occurred because, in striking, the die sort of bounced, slipped, or vibrated. If this is so (someone please correct me if it is not), doubling, or tripling, as strong as it looks on the mintmark would surely be at least slightly evident elsewhere, especially nearby. A mintmark punch could likewise bounce, I would think, which would be a little different than replacing the punch for a second try for a true repunched mintmark. Could this be what happened?
