Thanks for the input. I will get more Zip lock bags and use them for the coins in my safety deposit box. I think that mostly I am disappointed that they are not in as good of condition as when I purchased them. They are not bad, but I can see some changes and some toning. Since I am a collector, some of these coins have been in my possession for twenty plus years. I know that I have toned and tarnished a little over those twenty plus years.
