For the copper experts: can anything be done about this spot?

It'd be nice if there is a way to either remove or minimize the spot but if not, it'd be nice to at least neutralize it so it doesn't get worse. Thanks in advance.

    It's definitely more black than green but up close, I think I do see some very minor verdigris with a strong loupe.

    A lengthy mineral oil soak might loosen the green and I wouldn't worry about the black.

    If the black bothers you sell the coin as otherwise you'd need to hire a professional...

    It looks like active corrosion. The surface of the coin has probably already been damaged.

    From what I can see, it would be impossible to safely remove it. Mineral spirits or old formula Blue Ribbon would help neutralize it, and if afterward you want to carefully work at it with a rose thorn or other small, pointy non metallic object, you might minimize it.

    Why don't you send it to the "conservation" service ATS?

    Could be some PVC (polyvinylchloride) residue on that coin, too. Maybe spent time inside one of those notoriously venemous soft flips. Coins come into the shop in those dastardly holders.
    What the previous posters have shared is really good stuff. If it's worth "fixing" have a pro do it. If it's worth experimenting on and losing, well that is "A GAMBLE" . We take risks. But we hedge our losses with great advice.

    What?!?

    You mean a doctor can't even cure what ails this coin?

    Mineral spirits is something I haven't heard before.

    Thanks everyone. It'd sure be nice to save it, but since this is just a 1903 in ~AU58 that I picked up for $9, maybe I might try one of these suggestions and see how it goes. Won't be too expensive of a lesson if it all goes wrong.

    Ha! We could start our own "conservation" service.

    My momma always wanted me to be a doctor!
