Environmental tarnishing/staining/toning (take your pick). Could be from being buried in soil or dirty coffee holder are anywhere in-between (could be anywhere). We see so very many similar coins perhaps they deserve their own section. Bottomline is the same; post mint environmental damage. This coin did not leave the mint looking like this. Not a planchet error or any sort of alloy mixture error. No numismatic appeal. Value: face.
