Old Blue Whitman Albums...need Advice

if it were me I would upgrade to the Dansco albums as I believe (and correct me if I'm wrong here) they cause deterioration to varying degrees. I had an old "silver stripe" Whitman album and all the silver coins' backs was all black and mucked up with stuff that got trapped between the backing and the blue cardboard holed fronts over the years. Again, Just my opinion.

I would move to something safer right away. Have you taken any out to see what the backs look like?

I would go with Dansco albums as well, but you should also consider Whitman albums if you like the blue. Regardless, you need to move away from the Whitman folders.

IMO - you should switch. I would go with the Dansco albums.

I have been collecting coins for 40 years, for the past several months I have been
working at a local coin shop. So I have seen thousands of albums.

The collections I have seen that have been in the worst condition have been in
whitman folder and albums. I know the members that like Whitman products will not
like hearing this. They will say they like whitman because they like blue,
If you read enough of their post they have hinted that Dansco albums are better.

I have seen both Whitman and Dansco Albums, that have had coins in the for 20 plus years
and the Dansco albums seem to hold up much better. Of course the condition that you keep
the album in, and the amount of use, is going to have a impact on how either of them hold up.

So for me I use Dansco albums, with slip covers, then store each album in zip lock bags.
Of course then store them in cool dry environment.

Edit - I forgot the Key date question.

If there is any worry about your key date coins. I would put them in Air-tite capsules. Or have them slabbed.
Possible things to worry about, might be environment that your coins are stored or security. Some collectors might not be able to store all their coins in their bank box, so putting key dates in air-tite type holders and putting them in the bank box could be a good idea.
