[QUOTE="kanga, post: 24700433, member: 9270"]I need to step back a moment and get a basic understanding of how PVC interacts with a coin. For this I'm going to limit my thinking to coins with a silver content. 1. Is what we call "PVC damage" a chemical reaction between PVC and the coining metal? 2. Since most modern US silver coins are 90% silver and 10% copper, are both those metals affected by PVC? 3. Does the removal of the "PVC damage" also result in the removal of the coining metal, i.e., pitting of a coin's surface? 4. Anything else that I couldn't think of?[/QUOTE]
