1941 S Jefferson

[Ronald Ozimek]

I am searching an uncirculated roll of 1941 S nickels & found this unusual coin. The back of Mr. Jefferson's neck seems to be missing material. It looks like a tear is rolling down from his eye and his chin also looks rough & under the right light looks a bit like a beard. The back of the coin looks normal. Is the likely cause of this defect a die breaking down? Anyone seen this before?

Evening Ron,
That's remanants of a die clash at the chin and above the Queue

the parts the arrows point to are die erosion and fatigue. remember those dies are doing some heavy lifting and there are going to be some side-effects. jeffersons are kinda known for extreme version of the aforementioned so you'll see these things again.

like eaxtellcoin mentions, there may be spots on the coin where clashes were and the workers did die abrasion which also degrades parts of the design.
