    I realize it will and always be a detail graded coin but my question is can one of the main grading companies conserve this coin? Pcgs , Ngc or Anacs?
    in the light and in photos you can see the green coloration in many areas.
    it is otherwise has decent detail. it is Graded VF-Details by Ngc.
    I would like to get the green to go and stay away though. Is this a possibility and who would be the best grading company to use?
    I am into her for 100.00 so I thought that was ok for the grade . Also i was having a hard time photoing her so hope these photos will give you all a good enough idea.

    thanks for the help.

    I would be very careful. I have seen corroded coins that were "conserved" that had all the corrosion stripped off leaving very little coin left.

    Good advice. IMHO I'd leave it alone.

    The corrosion is below the surface. Messing with it will make it worse.

    ok another question then was this a fair deal at $100? It still has some nice details in hand.

    If you can save up $300 for one, $100 is too much.

    If the green corrosion is still active, you won’t have much in that holder in a few years.

    Verdicare would help it

    I had coin that looked sort of like that, soaked in verdicare for a few hours, then used a locust thorn (bigger and easier to hold than a rose thorn) to pick off the softened green stuff, then back to soak, pick, rinse, repeat. got most of the verdigris off and its held up pretty well. It was this Hibernia copper, this image is pre treatment, I don't seem to have a post photo, sorry.

    It's 240 years old. I wonder how much worse it would get in anyone's lifetime. Seems like it might have already been "conserved" anyway. (How could you tell?)

    Leave it. Any corrosion that is removed will leave behind equally unattractive pock marks and surfaces.

    I guess it's leave it alone ? What's Eddie say : eddieXmasVaca.jpg

    Verdicare would at least stabilize it

    Study the coin and it's issues, make a decision, stick to it... The best answer will be your decision! Best of luck

    It looks like it's already had corrosion removed before. I doubt that if you treat it kindly, you could damage it further.

    This Nova is already heavily corroded. If you are going to keep the coin, then you have absolutely nothing to lose by cracking it out and removing active corrosion and stabilizing it or sending it in for professional conservation. I think if you just let it stay in the slab, it can only get worse, although I guess if it's kept in a low-humidity environment it might be stable for a while. If conservation, by you or the pros, makes the coin look worse, what's the big deal? After all, you only have $100 in the coin.

    OTOH, why not sell it on and get yourself a healthy specimen?

    I agree. Sell it and buy another, healthier specimen.

    I agree, if you are not happy with it, sell it, add in what you would pay for conservation and you would have enough to get a nicer one.
