Goldeggsandham New Member United States 45 Posts	Posted 09/05/2022 4:39 pm Has anyone's coins been damaged by PVC pages despite coins being in mylar holders? It's alittle early for me tell if PVC pages are damaging my coins through the mylar. While browsing the coin supply market, there are more PVC pages available than mylar holders and flips. Polypropylene pages are usually harder to find, usually lacking thumb holes, and tend to be expensive. I just can't find a straight answer on whether or not PVC pages still damage coins through mylar. Thanks! Report this Post to the Staff

hfjacinto Pillar of the Community United States 7273 Posts	Posted 09/05/2022 5:30 pm If improperly stored, PVC will migrate onto coins/currency, etc. If you have coins in a 2 by 2 with a mylar, the PVC won't migrate onto to a coin, same with currency in Mylar sleeves. To be safe, I have my low cost coins in an album which has PVC pages, but all are protected in a 2 by 2. (BUT these are low cost coins, actually stuff I picked up from my travels). My expensive Raw coins are not near PVC. My Slabbed Dansco 7070 with Gold Page My Slabbed IHC Set My Slabbed 20th Century Type Set Report this Post to the Staff

Sap Moderator Australia 16816 Posts	Posted 09/05/2022 8:04 pm The plasticizers in PVC generally don't go all the way through mylar film, but they can go partway - which makes the mylar film of a 2x2 sticky, making it unpleasant to look at and hold, and can cause the 2x2 to stick in the album page, so the film tears and breaks when you try to take the 2x2 out again. So it might take a very long time to ruin the coins, but it probably will ruin the 2x2s much faster. Don't say "infinitely" when you mean "very"; otherwise, you'll have no word left when you want to talk about something really infinite. - C. S. Lewis Report this Post to the Staff
sel_69l Bedrock of the Community Australia 21786 Posts	Posted 09/05/2022 8:42 pm Perhaps 20 or so years ago, some of my bronze coins in Mylar 2x2's did in fact suffer from plasticizer gassing from PVC pages. Indian Quarter Anna red and red brown coins darkened considerably, over a period varying from 5 to 10 years, and this toning (which annoyed me), is not reversible. To save the rest of my collection, it was a no brainer to replace about 100 PVC album pages with non PVC archival quality equivalents. No further toning deterioration of any coins in the collection since Report this Post to the Staff
