Is this environmental or a planchette error?

Found this coin roll hunting and I'm still trying to decide if it's a planchette error, or environmental damage. Some of the petting that is impressed deeply still has copper and luster I don't get it.

    Without a doubt environmental damage. It’s basically corrosion and zinc rot.

    Obvious damage/rot.

    Spend it fast as it is disintegrating. :p

    What it is should be painfully obvious.

    corroded zinc is black.

    as zinc corrodes it falls away from the surface like rust flakes off and not like the surface corrosion/tarnish of silver

    Obvious extreme environmental damage.

    All glory is fleeting.

    If it were a planchet error, the strike would be over the top of the defect. [The planchet exists before the coin is struck.] You should be able to tell by the raised dings and damaged devices that the damage occurred AFTER striking.
