From those pictures it looks like split plating exposing the zinc core.
Eventually zinc rot will set in.


Correct typo

Difficult to tell from the photos posted. Do these areas look silver-ish? If so, you may have a case of split plating. One or two closer-in, large and sharp photos may tell a better story. Thanks.

yes +1 for split plating. It's a no value added occurance with newer zinc core Lincoln cents. sometimes the die breaks the copper plating in the strike.

The collecting community adopted the term "SPLIT PLATING". Till all studies will be finish we will say split plating. I am not involved in this study but I talk with some involved. Seem at 80% to be s plating defiance. Seem to be attributed to the material electrical resistance. Not yet resolute.

The cents planchets are delivered already plated by third party of the mint. here follow the explanation from the ANA learn Academy. So is not a mint default, error, variety or strike.
