1957D Lincoln wheat penny with some possible errors .....I don't know exactly what it was struck through...but it's looks like it happened before the lettering of the coin was struck being that it looks like it was struck under the E instead of over it... What might have cause this error....
The planchet had a lamination error, not a struck through, before it was minted. Nice find. Save and protect it.
Detached lamination for sure. https://www.coinworld.com/numismati...numismatics-error-coins-collecting-hobby.html More info: https://goodcollector.com/articles/lincoln-cent-lamination-error/
