The Coin Collector albums have clear acetate slides that cover each side of the coin making both the obverse and reverse visible. The Coin Collector albums do not contain PVC.
Wouldn't this make it as safe as a Dansco?
I think coins in these albums look great, but I do not believe any normal album, no matter who makes it, can be totally safe if you live someplace where humidity is high. Some web-homework finds people saying in the SW States, that these albums can be had for a long time with no toning effect.
If you do any reading of "Intercept" coin albums, holders, etc. they make an interesting statement that although toned coins are pretty now, they are in the process of oxidizing and turning black. I have a feeling that one day mint state, mint luster coins will hold a premium.
The 2X2 holders seem the only way to economically store a large number of coins where they will not contact anything hydrophilic in nature.
