Active PVC contamination??

[gbsten]

I was looking to purchase a MS graded 80 CC and ran across this item on ebay. (200348967499) Sorry, I don't know how to import the image, but for those of you that don't mind checking is that active PVC on this coin? Image #3 (around the mint mark) looks really bad to me. This looks like a newer holder, I can't believe it has PVC. Could this just be a strange toning pattern or is it PVC??

No.It looks like toning to me. And there is very little chance a pvc contaminated coin would get through NGC grading. I'm not saying it can't happen,but pvc contamination is one of the main things they look for .

There's definitely something going on there. Not sure it's PVC, but not sure it's toning either. Here's the pic.

If in doubt, soak it in acetone and then you can be sure it's PVC free.

Correct me if I'm wrong, but isn't green one of the more advanced toning colors? Looks like I see some small areas in the hairlines also.

That might actually be mild corrosion, which, for the record, does get through grading quite often!

prudden, it does not look like toning to me. Yes, green is one of the colors a coin can tone, but it isn't going to look like that - that has much more the look of mild corrosion or possibly PVC. There is just no way to tell what it is from teh pictures alone. A little bit of green stuff, as Douglas mentions, does get through on occasion. This appears rather minor, and I'm sure that most people would miss it when looking at the coin for 20 seconds.

I think that, most of the time, the graders do spot corrosion, and simply factor into the final grade.

 

I remember the poly-bag inside the PVC flip now. And a few years back, they switched to non-pvc flips and no polybag. But, the particular brand they were/are using is a very thin ply, and so its a little more flexible than a lot of the other, more rigid mylar flips, making it seem like a PVC flip.

Now that I see that close up of the tail area,I think it very well could be pvc or corrosion. Spoke too soon.I was looking at the full pictures and didn't check the others. Man,gotta look closer next time I spout off and quit being lazy.Sorry.
