Both of those are excellent points. I am going to reach out to them and ask. My dealings with them in the past has been very positive and their customer service has been very helpful. I'll post what I find out here.
I've never been into albums much but remember it didn't stop rim toning on the ASE album I had. Of course I can't say how bad it would have been without it so maybe it did help a little. I agree, I've long believed them to be one of the poorer methods of storage in terms of how well they protect the coins.
ASEs, because they are produced in such huge numbers, serve as a reminder for modern day collectors just how reactive, how prone to toning, silver actually is. Many are't aware of that or have forgotten since silver coins, in large numbers anyway, ceased in 1964. As a comparison regarding your comment, I once took a roll of ASEs, put them all in Air-Tites, and then put all of them in a sealed Tupperware container. That's about as good as it can get when it comes to protecting your coins. Within 2 months, every coin had toning around the rims. And that took place in Utah, the 2nd driest state in the country. So as a rough comparison, the slip case didn't make any difference at all.
How about the newer albums that are still made from cardboard. Have they done anything to the material in terms of treatment or different product to lessen the album toning factor?
I completely agree, especially with the essentially pure silver coins. I could certainly believe that.
