When PVC decomposes (and this is accelerated by heat), vinyl chloride monomers can vaporize and deposit elsewhere, so finding PVC inside 2x2s isn't very surprising. When vinyl chloride decomposes, hydrochloric acid is released, and this will etch coins.

YES! That's why I think there is just no reason to mess around with PVC-anything.
This situation has taught me a lesson. Don't even bother with PVC vinyl pages, much less PVC flips. We have some auction companies who continue... even today... to put coins into "temporary" PVC holders. Why do they want to take that kind of risk?
It's such a serious problem that if someone wants to link this thread ATS, I won't mind at all. Get the word out. The crusade reminds me in some ways of the "coin doctor crusade", except that I would bet this vicious, insidious substance has ruined FAR more coins than coin doctors ever have.

I bought a small collection a few years ago that included a 1964 French mint set. The coins were packaged in a PVC sleeve, and I was using acetone to get green goo off my hands after removing the coins.
Nice salvage job!
