    NCS might be able remove all the active green corrosion, but other than that, I think this thing is pretty much ruined.

    I'm not sure how accepted these techniques are, but you can check out MetalDetectingWorld.com's Cleaning Copper and Bronze Coins info.

    I believe I would soak it in acetone.

    I'm afraid she'll be just as ugly with the gunk removed.
    Maybe you can prevent any further deterioration at least.

    Good luck!

    That is one nasty case of corrosion. If it has eaten into the surface to the extent that it appears, only an active approach like an oil bath and an orange wood stick session would help. Sorry.

    Duiguy, I feel that's beyond conservation so I wouldn't bother with NCS.

    You could buy a can of copper metallic spray paint! image

    I've soaked a large cent with that kind of active PVC contamination in olive oil for weeks and weeks, gently using a q-tip rolled over the coin's surface.

    My results were noticeable, but it needs more time still in olive oil.

    I don't think that can be helped that much, but I'd try starting with Blue Ribbon applied liberally with a Q-Tip, then blotted off. Follow that by a good rinse in acetone just to see if anything else can be removed. Then a long soak in olive oil. But that seems like a lot of work for this piece. It will never be a pretty coin. image

    Don't use olive oil. What ever you use always use acetone first.
    it remove oil and other contaminates that may react with your cleaner. You are not going to get good results what ever you do with that one.
    Give the laziest man the toughest job and he will find the easiest way to get it done.

    Acetone, alcohol rinse, then olive oil for a month. Followed by acetone, alcohol, hot water and clean air blow dry. Will never be beautiful, but will be much better. Cheers, RickO
