[QUOTE="jseaman, post: 137398, member: 5538"]Noooooooo :eek: Don't use plastic bags for storing coins!! Most types of flexible plastic contain PVC - this is a chemical that allows the plastic to be flexible - it is the stuff you smell from a new shower curtain. It is also the stuff that, in warm humid climates, causes nasty green spots on coins ... and that green stuff eats at the metal causing permanent damage. It usually takes a few years but the damage is forever. Many "flips" that are made for storing coins contain PVC. Be careful - make sure they say "PVC free" and don't have that odor about them. If they are nice and flexible, it isn't what you want. Somewhere from stiff and brittle to hard plastic is desirable. Almost all cardboard 2x2s are OK and they are very inexpensive. Almost all paper and cardboard envelopes have acids in them. Don't let them come in direct contact with coins![/QUOTE]
