1971 Half Dollar - Annealing Error?

Brando898

This 1971 Half Dollar caught my eye. At first, I thought it might be PMD, but maybe it's an annealing error. Any thoughts?

That coin was in the ground for a considerable time, and the mark on the obverse is from the metal detectors digging tool...PMD all around..... Cheers, RickO

Agree
It is known as Environmental Damage.
Still worth 50 cents though.

This, or possibly a parking lot special. Either way, exposed to the elements and PMD.
