Storage Containers, Which Are Safe For Coins?

And as to storage, you should be more specific. Just putting coins in a large plastic container may not be wise if that is your intension. They should all be kept separate from each other as much as possible. If each coin is placed in a 2x2 type flip, for example, they will not bump, collide or bounce into others.

Oddly enough I'd keep them in shoe boxes over a plastic container such as a large bin or one of those plastic sealed type containers. My reasoning is pending on where you store your coins, if moisture is present when you close the plastic container, it stays there. Evemtually may attack anything you put in there. At least a shoe box can breath so whatever moisture is there when you close the lid, it will still be able to seap out.
Presently all my Proof and Uncird sets are in large cardboard boxes. And have been there for a long, long time. Items I've put in plastic storage containers have in the past warped, tarnished and some leather gun holders turned greenish and fell apart. Since that I've kept coins in cardboard. For 2x2's I use those large, two row, cardboard boxes by Whitman.

Carl, it's funny that you keep them in cardboard!, I thought by doing so I might be doing more harm, but maybe plastic is worse?
I've also thought of putting them in acid-free cardboard boxes I've seen in craft stores, maybe thats an idea?
I've havent seen the intercept boxes, will look into that as well, thanks Fred!
hope all had a good weekend
