2000-P Maryland Quarter Dark Brown On Both Sides

TY for the info. It looks like someone spray painted each side. The dark brown color is the same all over both sides except on the high parts where some has been scraped off. Maybe someone did spray paint it. :) Can it be PMD still given that info? TY again.

to the CCF!

looks like a burner to me, this will happen with copper or nickel when it is heated to red hot then cooled, the metal is oxidizing from the temperature and addition of oxygen or hydrogen.

Something like that.

I know if you heat a clad quarter to 1200F in a forge or a fire hot enough, with a torch ect. , then drop it in methanol, the methanol will boil, then stop boiling (Leidenfrost effect) then really boil for about 1 second, then stop, and the quarter will turn copper as this happens.
the copper core will move to the outside of the coin and plate copper over the nickel. without the methanol used as an oxidizer, you just wind up with a really ugly matte black or grey quarter. it's this effect with the near molten metal I guess and the brief shield of the vapor layer around the coin, and then it's collapse that pulls and places some of the copper out from the center and on top of the nickel outer layers.

Anyways this looks like someone heated it up to see what would happen and let it air cool. maybe put it on ice, not sure. but air cooling will give it an appearance like this, I am sure H2O will do something else with the addition of the hydrogen, but could be similar result.
