Can slabbed coins degrade while sealed in the slab?? I have them in a slotted cardboard box inside my safe. Anything else I should be doing?
Thanks in advance

I keep desiccant in my safe as an added safeguard against moisture. -
Yes they can. Carbon spots, fingerprints, etc.. can grow on a coin inside a sealed slab.
Like Maineman said, protect against moisture and humidity. I have an open box if rice in the bottom of my safe. I have even used air tight/waterproof ammo cans, the ones with the rubber gasket/seal. Believe it or not, even a meat/food vacuum sealer. If you have coins/albums/slabs in storage for a long time, ones you don't pull out and look at often, seal them in a vacuum sealer. Just my two cents.Comment

And one thing I forgot to mention is that I rinse all of my copper in acetone before putting in flips....I feel it helps prevent fingerprints from appearing later on.Comment

A few months ago some one posted a link, to ebay I think, of a LC in a slab with blue/green tentacles growing on the coin... So things can happen... If memory serves me correctly the only thing I can think of that would cause that on a copper coin is silver nitrate... The dessicant is a good idea whether in a safe, box or a drawer... Any time a door, lid or drawer is open that exposes the inside to what ever is on the out side!!!Jim

Avoiding heat is also important, they mess up faster if they get warm or hot.
Slabs are probably better than flips but cents do best in tight full plastic tubes, all unc reds so no contaminants from other coins and a sacrificial common one on each end. The end ones will haze on the exposed side.Comment
