I would be wary of having coins in containers with cardboard. Ideally you want the coins to be in an airtight envelope made of plastic to minimize any chance of oxidation or reaction with chemicals in the air.
Cheap, retail coins like you would find in a Whitman collection are not generally going to hold value well. Sometimes you can sell a collection and break even if you have a nice complete set, but in general VF coins with common dates will not appreciate at all.
Investment coins usually are high-priced items that sell for thousands each, not the sort thing you find in Whitman folders.
In general, collectibles are bad investments in the US because IRS rules tax gains as ordinary income. So, unless you sell them under the table or have really low income, you lose a lot of your profit.
If you enjoy collecting, focus on the fun of it, worrying about investment in coin collections is a joy killer.
A Parting Anecdote...
When I was a kid I painstakingly assembled a lot of BU rolls, because that was the hot thing back then. I wrote on them "DO NOT OPEN FOR 10 YEARS". You know how much a 1980 BU roll of Lincoln cents is worth now, 40 years later? $2.00 on eBay. Some days I spend more on lunch than the worth of my entire Lincoln cent collection.
