A 1776-1976 Eisenhower dollar that has considerable damage on the obverse is this PMD or some type of lamanation error? I have no Idea. WIN_20240710_14_43_20_Pro - Copy.jpg

In my opinion, it's PMD. It appears to be heavily pitted, and most of the patina ( shiny luster) is gone.It may have been in the ground or an acid experiment project. if that is a green style fungus looking material, it might be verdigris. It shows up when coins have been mishandled, exposed to extreme weather changes and/or close to high humidity and salt air.

Thanks, I thought I would put it out there with wishful thinking.
