I got this half today when I stopped by my bank. I’ve started asking for any they have when I’m in there. This one is a strange one. The inner layer seems to be eroding. It is consistent around the full coin, and reeding is present in most of the corroded areas even though I can’t get it to show in pictures. Any idea what causes this?

Some acids will do that, it attacks the copper core more than the copper nickel outer layers.

Yep (thumbsu

Yep, that's exactly right.
