Does storing coins in an album like the Dansco cause silver and copper coins to darken over time? I'm not talking about the bullseye toning like seen on the Wayte albums but just a darker finish because of not being in an airtight inert holder? I'd like to put some more expensive coins in the album but am afraid the nice color and finish will change.
Also I bought an older album a year or two ago but noticed some slots need a makeshift shim to keep the coin in the respective slot. For those with experience with the new album, is this still an issue or did they correct it?
