You can keep the coins in the plastic coin tubes for they are inert. The paper used to wrap coins is not. The ammo box has to go. There is residue of oils and other chemicals there and no washing the box out will not do. Coins have rims on them so they will stack and that is the part that touches the coin under it. Just be careful when you take them out of the tube, let them slide or fall onto a soft cloth and don't let them hit each other.When putting coins in the tube just take it slow and easy. It is not that hard to do. The coins at the end of the bank wrappers are toning, due to the box and also just to the air hitting them, the rims in side will too, for the bank roll paper has chemicals in them. Put all rolls in to plastic tube and store in a plastic box made of a hard plastic with a lid, not a soft plastic. The item in plastic that makes it soft and pliable will damage coins. Try to store the coins where the temperature varies the least. If you live in a place that has high humidity, get some silica gel and put it with the rolls. Take out the packs every month or so put in a low heated oven to dry them out and put back into the plastic box. You can get the silica gel from a coin dealer, or almost every piece of electronics comes with a small packet or at least used too.
