Crooked Memorial roof

[westnlas]

I came across this 1979 D LMC with a wave in the roof of the Memorial. No doubling, just appears the engraver got crooked with the line WIN_20220922_12_45_24_Pro.jpg

Or over zealous die polishing to get rid of a clash,

This area was not engraved, but I certainly agree with overzealous abrading of the die to be the culprit here.

Thanks a lot. So, I'm looking at single die for mintage numbers, then ?

[mustbebob]

This die probably struck between 500,000 and 750,000 coins. As far as when the clash and subsequent abrasion took place, it could have happened at any time during the striking cycle.

Thanks, I'll file it without a number, then. Appreciate it

There would not be any number to begin with. Varieties like doubled dies and repunched mintmarks get numbers. This one is the result of a simple part of the minting/striking process that is very, very common. Minor clashes and die maintenance is so common that there is no way to track these with a number.
