VERDIGRIS--Will PCGS slab a coin with verdigris?

Supposing it's just a spot, here or there. Is it simply a matter of degree? Supposing it's on a scarce key date. Is it also a matter of that? What are the "rules," if, indeed, there are any?

PS: And it's no answer to say, send it in for "conservation," first, as, there are no conservation techniques that can rid a coin of verdigris (at least, none that I'm aware of; that is to say, none that wouldn't simply replace one type of damage to the coin with another).

    Verdigris if not too far gone can be conserved.

    If not conversable, they would probably "Genuine" it.

  • I have some indians with verdigris on them in pcgs slabs, I can probly snap some images and post them here in a bit. Ive sent in coins with pvc to pcgs for spot review before so I know thats also gotten past as well.

    The verdigris could have grown in the holder too.... would be interesting to see it conserved and hopefully it didn't eat/pit into the metal.

    PCGS graded this one just as it is. I bought it a few weeks later and sent it back. PCGS cleaned up things (see the "after" images).

    If it's a little unobtrusive spot, then in my experience they will.

    This may be PVC, but it's not verdigris.

    You are probably correct, Steve. Verdigris is associated with copper and this trime was only 25% copper.

    I've always had a tough time distinguishing the two. PVC haze is easy. But when green spots arise on coins with copper I just don't know.

  • lkeigwin: thanks for that before-and-after illustration. May I ask what grade they gave that?

    Steve27: what about that spot at 9:00 on the reverse, that sure looks like verdi to me. I know this much, though, sometimes it's an easy "off" with some acid; other times, when it has a 'hold," fahgettaboudit!

    The trime was graded AU55.

    Beautiful. I'll say they used acid on it, judging from that toning it lost. That's often times the quid pro quo.

    I have one of these, an 1856, I believe will go at least XF. I have to ask, as long as you picked this series for your illustration, where are the star "ridges" on these? Are those the areas midway between the points?

    I'm not sure I get the question. Are you asking about the obverse star outlines that were introduced with type 2 in 1854? Or the shield bars and stripes?

  • Lance, mine is a different "type" than yours, but the grading guidelines for all these in my Redbook mentions "ridges," and I'll be darned if I can figure out what those are.
