I need your help again! Found this in a quarter roll, and figured it deserved a second look. 2000 D Massachusetts Quarter that appears to have sat in an acid bath. Is there another explanation for this though? Both sides are copper colored, as well as the rim. It appears as though there's still some silver color in spots... so I doubt it's a clad issue.
The reason I posted it is because there's really good detail on this coin, as well as what appear to be die cracks running above and to the right of Washington's profile. Wouldn't these disappear in a bath?
