[QUOTE="GDJMSP, post: 7763482, member: 112"]The problem is with the wording that companies use in their advertising. People reading that wording may or may not understand what the company really means, because to the words have one meaning, and to those reading them the same words have a different meaning. Short and sweet, PVC is a very hard and very rigid plastic. And it has no plasticizers in it. BUT - if you add plasticizers to PVC then the PVC becomes soft, pliable, flexible. And almost all forms of vinyl are made from PVC, but is made from PVC that contain plasticizers so the vinyl is soft and flexible. Most album covers, 3 ring binders, things like that, the vinyl covers contain PVC with plasticizers. With coin flips it's the plasticizers that are the problem, it's the plasticizers that create what we call PVC residue that harms coins. So, when buying coin flips, as long as the company states that the flips contain no plasticizers, then you don't have to worry about PVC residue getting on your coins. And it doesn't matter if they say archival quality or museum quality, that's just advertising and they pretty much both mean the same thing - that the flips do not contain any plasticizers. It is also important to understand that archival/museum quality flips have their own problems, they too can be and are harmful to coins. But they are harmful in different ways, they are very prone to scratching coins, causing hairlines on coins, and causing wear on coins. So what's the answer ? It's quite simple - don't use coin flips - at all ![/QUOTE]
