One ugly MAD Lincoln with a bad case of pox and sumushies... MAD means a misaligned die, just loose hits off square. the details are all there so isn't an off-center strike, reverse has to be effected in same way.
And I think it ran into our favorite coin villain:
Quote: I thought pox were bubbles and these are holes. I'm still getting used to all the vocabulary. I wonder what caused them?
Those holes used to be bubbles until they popped. Most likely, the intentional damage broke through the copper plating and exposed the zinc core to the elements. It is called zinc rot and will start as small bubbles created by corrosion gasses. Eventually, the bubble will break and what's left are pits like this. At this stage, it will continue to rot until the entire coin is eaten away.
Use the forum search and enter "zinc rot". There are many examples and much info posted.
