I'm sure we can all agree on one thing - PVC is cruel! If there is any obstacle in coin collecting I hate the most, it is encountering PVC Damage. I'm going to talk about PVC Damage and how to prevent it.What is PVC Damage?
Polyvinyl chloride, or PVC is an additive used to make plastics softer and more flexible. It is in plastic flips and those plastic sheets that are put in binders. I don't recommend using coin flips, and if you are going to put your coins in a binder, put them in 2x2 cardboard holders first! If you have a very expensive coin, go the extra mile and get a hard, round case for it. PVC only exists in soft plastics.What Does PVC Look Like? How Do I Remove It?
PVC Damage can be a blue-ish green, gray or white color. Copper is most vulnerable, followed by silver, gold or platinum (Susan Headley, coins.about.com). If you see PVC on your coins, throw away all plastics that touched it. Keep those coins away from your collection so it won't spread. If nothing is done about the PVC, it will eat away the metal of the coin until it has destroyed the coin. Here is what I do to remove PVC:-Use Acetone (found in most nail polish removers. Use gloves and eye protection)
-Soak the coin(s) in acetone for 24 hours.
-After the coins have soaked, gently rub a Q-tip (without plastic) on the damaged areas.
-If the PVC doesn't come off, try again with more force, but be careful not to damage the coin more.
-If the PVC still doesn't come off, soak for another 12 hours. The next time it should come off.
If Your Coins Were Exposed to A Coin With PVC, Clean Them Anyway!
A few days ago I was looking at a few of my Indian Head Cents when I noticed 3 had PVC. The next day when I was cleaning them, just in case I cleaned the other sides. Just as much green showed up on the Q-tip on the PVC infected side then on the reverse. Just because you can't see the PVC doesn't mean it is not there.If anyone else wants to add anything I didn't mention, please do so in the comments.
