The middle of the Reeding is sunk down ? And on reverse side it's missing part of the rim? Wondering what this is called especially the Reeding issue? And has a odd grey color

The coin has been sitting in an environment that corroded the copper but left the nickel cladding relatively unharmed. Just a damaged coin unfortunately

Your coin is showing evidence of environmental acidic conditions. On the coin's edge, you can see where to acid has eaten into the copper. Post mint damage, a spender I'm afraid.

Appears to have been dipped in acid. The acid will remove the copper core faster than the cupronickel cladding, leaving a depression as you're seeing around the edge.

I'm confused because if it is corrosion why is it so perfect and not uneven..? And I didn't know the ridges on Quarters were cut below the rim I thought they were only cut so far out around the coin not inside as far as it shows? Can you please explain

@drag, on quarters, imagine the layers of clad and copper as a sandwich. The cladding is the bread and the copper is the tuna fish or whatever filling in between. Also, the reeding is not cut into the metal, but rather forged so there will be evidence of this metal movement more than just on the surface of the coin's edge. Hope this helps.

The acidic environment will also attack the surface of the metal equally, leaving the impression of reeding visible on the corroded area.

We see this type of damage fairly often on here. Another clue is the really dark and pitted obverse and reverse. It's an indication that the coin has been sitting in a harsh environment.
