Got this 1984 D coin in change yesterday and it was as if just taken from new roll...

For the fun of it I thought I would check for the chin and doubled D errors(not), but noticed this and as many unknown# of cents I have looked at, I have never noticed that the strike from the IGWT pushed metal up below them higher than the letters. I'm sure it happens, but just never noticed it. The shadows from the light is what made me notice it, so enlarged and sure enough. I tried to check it at an angle with no success. Would this mean the planchet might have been somewhat loose or how did this truly happen?

Split plate, the copper plating on the zinc cents stretches and bunches up around the numbers and letters when struck. The effect is called split plate doubling as often the copper plating will get stretched too far and split exposing a thin sliver of the silver zinc core. Super common on the zinc cents.

Also, often termed (right or wrong) machine doubling. Cheers, RickO
