Coin storage question.

Placid

I gather that airtight storage is the best. So would storing slab's in a tupperware container be airtight?

The best way to store coins is in a dark, cool, dry, unchanging environment, with dry being the most important. I dont think a 100% airtight container is necessary if they are already slabbed.

A bank safety deposit box is usually ideal, I also have a few small packets of desicant(sp) in the box and I have never had any problems whatsoever in over 25 yrs. If you store your slabs in this way, tupperware containers are probably unnecessary.

Tupperware may be air tight but there is still air inside it that could tone or damage your coins. I keep my slabs in PCGS storage boxes and in a dry cool place. I keep anything not in slabs in intercept holders.

Slabs have air in them don't they? The one I dropped in the bathtub a few weeks ago got a little water in it.
So putting the slab's in a tupperware container with some silica bags won't help any better than just the slab's in a pcgs box with silica?

LMAO!!!!! just when i'd forgotten about the "bathtub incident" you remind me!!

What on earth are you doing with your proofs in bed?


They might get some lint on them or something!

Did you practice safe numismatics? You can't be too careful these days.

Of course I practice safe numismatics ... I never get one out without an Intercept Shield!

I think I need to go wash my hands now.

I don't believe slabs are airtight. Putting them in a tupperware would seal off any outside air into the container, but what about the air trapped inside? Also with varying temerature areas, the air sealed inside will expand and contract and that could impact the slabbed coins. Condensation is a possbility too. That is why silica is needed sometimes. So to answer your question, the use of it will make it airtight with regards with the general atmosphere, but not airtight with regards to trapped air.

How about arranging the slabs next to each other 4 or 6 in a block and then vacuum sealing them with a food saver vacuum sealer? Then they could be stacked easily and airtight and waterproof.

So what does the tub-dropped slab look like now?

I broke it out that night and used a hair dryer on the coin.

I always thought that gases move easily through slabs. Not sure if a second container can help, but it can't hurt. This could be crazy but a person could put in tupperware with silica and the the Intercept Shield pages they make for albums, above and below the slabs. There is so much to protecting coins it's hard to know whats best. How did some coins make it 100 to 200 years and still look as nice as they do? They didn't have this stuf.

My mother kept her coins in the freezer in a plastic bag for 20+ years. None looked toned either.

I have most of my mint state and proof coins slabed and in PCGS boxes. I have a type set, proof cents, and some odds and ends in a plasic leaf binder and my Lincolns, IHC, Washinton Quarters, Kennedys, Ike and a raw set of SBAs in a whitmans folders. The state Quarters are in 2x2 in a couple of 2x2 boxes. the proof sets and some commemorative are in a cigar box with no cover.

I keep seeing this statement in one eBay sellers items.

Does ngc have a new airtight holder?

That could be the cause of some interesting toning patterns!

Another very interesting thread, depending on the date of the coin, some of the couples on the board could be arrested for contributing to the delinquency of a minor

The best place to store slabbed coins is probably in the intercept slab storage boxes with the intercept slab shields around them.
As for raw coins, either an intercept or (my choice) an airtite. The black ring airtites are exceptional. Very attractive and will protect your coin well.
