I think I know the answer already, but, still want to make sure. Also, sorry to everyone who has probably seen a question like this a thousand times before. I have been putting my coins in SUPERSAFE self adhesive 2x2 flips & then putting them in albums made of PVC pockets/pages. Will this hurt the coins or does the PVC pockets/pages have to come in direct contact with the coin to damage them? Thanks.
Never heard of Supersafe flips, are they PVC (Soft floppy plastic) or Mylar (Hard plastic). If its soft, they are the dangerous PVC rubbish, if hard they are Okay.
If anything you have is plastic and made in China - its likely to be PVC and biff it.
If you have mostly cheap modern base metal coins, may be okay - but silver and gold - hell naw!
I love coins. Especially silver, gold and anything really old.

The SUPERSAFE cardboard flips are made of archival materials and include no PVC or harmful additives. The non-migrating self adhesive gives an air tight seal to protect your coins. I buy them from Wizard Supply online. I'm just trying to learn the science of PVC material. Does it have to be "in contact" with a coin to do damage or is it "airborne". Thanks for the reply.

If PVC would be airborne, we would be in big trouble as human beings, as our lungs would be filled with it. I think it's safe to assume that is not the case
I'm not a chemist, so this is just based on my own understanding, but I'm pretty sure the coin-destroying PVC reaction requires contact with the coin. The PVC doesn't spontaneously turn itself into acid otherwise PVC wouldn't really be safe for any applications (which isn't the case). If the coins are protected in a non-PVC flip, the risk of a reaction is pretty low. However, it's worth remembering that if there's even a tiny tear in the flip, your coin will be in direct contact with a PVC pocket and any damage is irreversible. I don't know if that's a risk I'd take unless there were no other options available (as seems to be the case in some countries).
Short version: It might be okay but be very, very careful!
Hi to whoever is reading this. Did you know that TYPEWRITER (on a QWERTY keyboard) is the longest word you can type using only the letters on one row of the keyboard.
