PMD - post-mint damage. (In other words, damaged AFTER the coin was minted.) Looks like it has been heated to the point that some of the copper plating is gone.
It could be struck on an incompletely plated planchet. A small percentage do show some sort of bulls-eye pattern. Only an examination under a microscope would provide the necessary evidence.
Mike is VERY familiar with the ANA. What he meant (as well as what he said) was he does not know what ANACS's statement means.
I have one just like it. Its not the first I've come across. I decided to keep the last one as I found it interesting that I keep comin across them, so I save them...just because.
The coin is not a broadstrike, so if its diameter is greater than that of a normal cent, it has been altered outside the Mint. It is impossible to get proportional expansion of a die-struck design on both faces.
