I thought PCGS would not slab a coin with active PVC?

    Interesting. What is the assigned grade?

    I doubt that's PVC. Looks more like good old corrosion.

    It's in a problem holder, yet I was under the impression PCGS simply would have sent this one back to the submitter.

    Looks like verdegris rather than pvc.

    Depends on who the submitter was?

    If i'm not mistaken that's verdigris, not PVC. In any case, I've noticed an increase in PCGS certified coins in my area of collecting (Mexico 8 Reales 1791-1821) with verdigris spots. I hope the standard hasn't changed.

    I agree, and the PCGS verdict seems quite appropriate.

    Not PVC

    Thanks guys. I defer to your judgment. The majority of the coin is, of course corrosion, yet I thought those two bright green flecks (top of the portrait) was PVC.

    .

    been wanting to discuss this for a while so i guess the time is now.



    verdigris by definition is a copper thing? yes/no



    can one really identify by visual only, no smelling or tasting, verdigris vs pvc on copper and/or when a coin has both?



    i agree the big spots would have made me at least think pvc but with the extensive corrosion, would have thought verdigris only.



    an acetone soak would verify pretty quickly as i doubt it would remove any significant amount of verdigris, if any.



    but this is about pvc vs verdigris vs details slabs.

    That doesn't look like PVC to me. More likely verdigris.



    Early copper, corroded. A genuine coin in a problem holder. No change in PCGS's policy.

    Verdigris is copper based, generally in the form of basic copper carbonate. Can also be copper acetate or basic copper chloride if it's near seawater.

    By the thread title I thought it had straight graded. PCGS did it right.

    corrosion and PVC are two VERY different animals. for your own benefit, you should get to know the difference one from the other.

    The thing I don't like is the TPGS's don't use the word "corroded." That coin is corroded. IMO, Environmental Damage should be reserved for coins whose surface is damaged by "whatever' yet the "whatever" has been removed. Green and red on copper is still "active." The theory behind not slabbing coins with "active" problems such as PVC was that it would CONTINUE to destroy the coin (at a slower pace due to the slab).

    Sure is ... a dead whale rotting away on a beach.



    Have it conserved and crossed, one of the TPGS's does not charge extra for conservation.

    When thinking about verdigris, think about the statue of Liberty. The same coloration can be seen on this coin.

    I see many, many PCGS coins with PVC.



    If you send a fair number of PCGS coins to CAC you will know that is the truth! It is one of the most common reasons for an otherwise nice coin not getting a green bean.



    That being said, the OP's coin may or may not have PVC. Cant tell for sure from the pic.
