This 1946 penny appears to be rippled. I won’t be surprised if nobody can see this and I’ve tried to mark the areas. Is it likely to be post mint damage or is it possible a planchette can be actually less than smooth?
I would go with PMD myself, mainly wear. The thicker areas of the coin ( bust) could act as the fulcrum effort. Maybe used in the age of penny parking meters, games, counting machines, etc. Jim
Looks like progressive indirect die transfer "ghosting" http://www.error-ref.com/progressive-indirect-design-transfer/
Paddyman is correct if the rims are flat level~ it doesn't rock on a flat surface. My answer was because I thought you meant it wasn't flat and you could rock the coin when it was on a flat surface. Jim
The reverse looks more like a ghost so Paddyman will get no argument from me. The obverse looks like PMD.
After reading Paddyman's link on progressive indirect design transfer, I can see Lincoln's head faintly on the first photo posted, so I would agree with him.
