I think we're working a bit too hard for a solution here, and some of us are not seeing things realistically. Go ahead and leave your coins exposed to the atmosphere. Maybe you'll be lucky enough to live in a place where the environment won't affect your coins. I know a couple of collectors like that.
For the rest of us, it's necessary to understand that the atmosphere is the enemy of what we're doing. And if it isn't today, a wind shift and local industry might make it so tomorrow.
If you do not have an airtight storage solution, you are playing Russian Roulette with your collection. For crying out loud, a volcanic eruption on the other side of the world is capable of raising atmospheric sulfur to a dangerous level for coins.
Food-grade freezer-rated ziplock bags (use the press-fit, not the ones with sliders) are simple, effective and sufficient to protect your coins. It does not need to be more complex than that. And you might not even need that.
But, do you want your coins to let you know whether such protection is necessary? How often do you want to check?
