PVC Residue - PCGS Code 99

DisneyFan

I'm watching the PCGS video and can see where PVC is highlighted. How did they do that?
Does PVC damage fluoresce under UV light?

I think that this is the subject video.

If it is, good question. I look forward to the responses.

You have the correct video. : )

I think they simply edited the spots in as they reduced the exposure and contrast of the image.

Tom - you have a high pass average with CAC. Are the coins that don't pass, was it because you didn't see the PVC?
