As I said in my initial post, there can be no cardboard or paper products stored with the coins. Now I don't know if the coins (in their hard plastic holders) can be removed from the cardboard packaging without damaging the packaging. From the looks of things I rather doubt they can be. I'm not suggesting that you damage the packaging of your set, far from it. But what you should do is store that set someplace else, away from your other coins and sets. Here's the thing, cardboard and paper is made with sulfur, and other harmful substances, as part of the manufacturing process. And cardboard and paper put off gasses containing the sulfur and other stuff. Those gasses are what is causing the toning that you are trying to avoid in the first place. So if that set is stored with your other coins, those gasses are going to get to your other coins and cause toning on all of them. No paper and cardboard means none at all - not even a small single sheet of paper ![/QUOTE]
