Spending some quality coin time this afternoon. Packing my slabbed coins back up for storage in my safe and I know there has got to be a better solution than this. I put them in Ziplock bags to help mitigate moisture. Surely somebody out there has a storage box that will accept different sized slabs and will close tightly like a Tupperware type box isn’t there?
Probably want to avoid containers that contain pvc, or other harmful contaminants, not that I bothered to check the make up of the Rubbermaid container that I have stored some of my coins in, for 10+ years, lol. Haven’t had any issues with it. I have had ‘issues’, aka toning, with keeping ASEs in the OGP, though.
I presume you use a dessicant in your safe. If you don't, you should. And if you don't, then sealing up your coins in a ziploc bag as you've shown is probably not the best way to do this. At the least, zip up the bag almost closed and use a straw to suck out as much air as you can, rapidly withdraw the straw as you finish the seal. The object is not to remove the air but to remove the moisture that is in the air. The finished result should look like the bag has been vacuum-formed around the coins/slabs.
I understand your dilemma and don't have a clue as to what the best method would be. @Publius2 makes a good point about desiccant silica gel packets and using a straw. I wonder if adding a packet of desiccant to each sip lock bag would be appropriate and speaking of bags, I believe Mylar Zip-Lock bags are available? Just a thought.
Vacuum seal bags, like food saver. Leave enough room to cut the seal and still be able to reseal it several times. This will remove moisture and should conserve for a long time. This is worked for my ammunition.
Well... I wanted to use something other than Ziplock bags. And yes, I do have desiccant in my safe. Here in the Deep South we get so much humidity in the summer and I have had coins turn fugly black on me before. I want a storage box that seals like a Tupperware container would.

Thing with plain Tupperware is the slabs will slide around and get scratched. I want a Tupperware type box with slots for slabs.
I would put them in the safe with desiccant or a desiccator and a tray with some copper powder to absorb any sulfides or oxides. If you seal the baggies or tupperware, you are sealing the outside air into them with your coins. Slabs are not airtight. You could get some boxes for the different types of slabs, or a general one for all types, then add desiccant and Cu power in the bottom as a 'getter'.
I searched every description I could think of and came up empty, zero, zilch. Let me know what you decide to do.
I already exhausted that search. Wish I had a Tupperware factory right now. I know what I would start producing.
Think of all the fun you will have dropping boxes on your toes, skinning your knuckles on plastic edges, not to mention a few sympathy tricks for your wife, or is that sort of thing verboten?
I probably won’t need sympathy tricks. I’ll get beaten to death for employing her Tupperware into my grand scheme.
If you should wonder why you got the trophy, it's because I could picture you sheepishly standing in your garage amid hundreds of Tupperware pieces and your wife, with a rolling pin in her hand asking, "What do you think you are doing with all of my Tupperware" and I burst out laughing.
@Randy Abercrombie, have you considered the Intercept Shield boxes for slabs? They're not plastic with locking lids, but they have some kind of technology to protect your coins: "The box contains Intercept Technology to provide active protection against contaminants. Intercept Technology acts as a neutralizing agent cleansing the air around the coin protecting it from the harmful effects of corrosion."
I've never tried it but using a food saver to vacuum seal coins with a small bag of desiccant might do the trick. You can reseal the bags too! Just food for thought!!!
