Do you think the reverse spotting is active PVC on this coin??

I noticed this 1940 Proof Jefferson for sale at eBay and had to check the reverse for obvious reasons whereupon I noticed the green spotting. Do you think it looks like PVC or just corrosion of some sort?? Thanks in advance.

    I'd say there's 2 active spots.

    It looks like it could be pvc but I doubt anyone could tell for sure from the pic.
    Pvc is just corrosion anyway. I'd say the spot on the rim is definitely gonna leave a mark.

    time to check out how good their guarantee is!

    That's too bad.

    the two you're seeing are obvious and there seems to be a few more to the left of the portico. with clear PVC such as this i'd be suspicious of any spot which appears as white/milky and i see a few of those, also. i'm a little surprised to see this since the coin is in a more recent NGC slab, perhaps 3-4 years old, and the spotting looks to "prgressed" to have developed inside the slab in that short time. the coin needs to be rescued if it is a clear Cameo.

    Sure looks like PVC, at least on the rim... Cheers, RickO

    The Rev. seems Cam but would the Obv. hit Cam? I know nickel is hard, but Pr surfaces so delicate - if this PVC were removed would there not be something nearly as unattractive left - loss of mirrors, etching or pitting or?

    Best,

    Whatever I'd just look elsewhere not worth buying into the trouble it's in.

    I think "inactive PVC " is likely an oxymoron. Neutralization is possible in theory, but the viscosity and thickness of most coin PVC makes it impractical IMHO.

    Looks like PVC, alright. And not just the two green spots. The light green milky look on the reverse too.

    I would pass on it. If it were mine I'd submit it under the guarantee. NGC will surely treat it but I think there's permanent damage under those spots and a payout is in order.

    It's PVC. If you send it to NGC under the guarantee, they may conserve it and reholder it if no permanent damage is present. This would be my approach.

    P.S. It doesn't look like a full cameo to me either.

    Is this something I should consider as a general rule with any graded coins. I ask because I have 2 $5 gold MOHs graded PCGS69 PR FS,one with 3 small red spots and the other with considerable red toning.

    Let's just say that you should always be alert to spotting. But there's no rule of thumb.

    Verdigris and PVC are no brainers...send them in. PCGS is great at conserving. Better than NCS, IMO. Red spots or red toning? We need to see photos. It may be nothing to worry about and nothing that affects the grade. Particularly at 69. And likely nothing that conservation can improve.

    With gold, a copper spot can appear red , buzzybest (to address your post).
    With nickel, a copper spot might turn green. I don't know but it's possible it could be verdigris.
    The rim itself looks to have a bit of metal missing. Or, consider this just an "objective" view, in the event it's not PVC. What is the composition of nickel ?

    The "corrosion of some sort" comment just made me look differently, I suppose.

    The two obvious spots look like PVC, and I see some tell-tale “green tinge” on the top of the porch of Monticello. The coin is probably already damaged, but a quick crack-out and treatment could save it.

    I agree with you with regard to spots. Unfortunately,the more fascinating red toned MOH gold I have does not show the widely dispersed perpheral toning in a photo. Even when looking directly at it in hand,you don't notice it until the coin is tilted.If you like natural toning,this is a unique gold coin that I have never seen before.

    That is a possibility as a nickel is mostly copper, not worth the hassle to me.

    It appears that when PCGS corrects active PVC, not all the bright green needs to disappear. Beats me, but that is the case.

    Pictures don't ever seem to tell the whole story, but sure looks like PVC on the rev rim, and potentially under the L O in MONTICELLO. Any greenish haze could be the result of the lighting used when the pictures were taken. But, with the presence of the other likely PVC spots, that makes any haze suspect.

    The before picture, then after the PCGS bright green repair. Check out star 11. Is this a satisfactory repair?
