Are Mylar 2x2 holders safe to use for coins and buttons??

will they hurt coins in any way??

Dont use anything that is made from or contains PVC. It can damage the coin and change its color over time. A goog book about coin collecting and preservation is the "Everything You Need to Know about Coin Collecting".
