Semi-original coin, has grime embedded, that was rubbed up and "oxidized", creating a black, sometimes bubbly, surface layer of silver compounds. This would properly be called "environmental damage". Rotated reverse of about 10-15 degrees; no reverse die clash. Has some tiny new scratches on the obverse rim from mishandling, and a few on the reverse rim. Probably a mid-level AU. Big thick coin weighs 6.3
grams
and would not budge.
