Best storage method for slabs in a safe deposit box?

    So that seems to say that dessicant in an airtight box would be fine.

    Just send them to me for storage....we don't have humidity in Las Vegas. My rubber bands turn to limp nothings after about a year. Dry out so bad that they don't work any longer. Silica does need to be refreshed so from a friend of mine in KC he keeps two batches and refreshes the SDB ones every month or so. He microwaves the ones that are being replaced to get the moisture out but needs to do that again just before he heads to the bank. Seems to work for him, very well.
    Then again since moisture is a big factor in toning perhaps you should have two boxes. One dry box and one "humid" box that the coins in there you want to tone?

    If you're very careful, you can add oil to the SDB and the plastic boxes will FLOAT on the oil.
    Try to remember you did it when you take out the box. :p

    What on earth did coin collectors do 100 years ago?

    There were no slabs, no safety deposit boxes, no humidiy control, etc.. Are we going to far in our efforts?

    Bags of silver dollars in canvas bags stored in Treasury vaults did just fine. On the other hand I remember viewing uncirculated and proof seated liberty coins in a ESNA (Empire State Numismatic Association) auction probably in the late 70s and every coins was either a deep iridescent purple or black. So..... I guess it all depended on conditions under which the coins were stored.

    I get bags of silica desiccant from my local Harley dealer.
    The incoming bikes are packed in an reusable shipping container with several bags in there.
    I'd guess each one weighs over 2 pounds.
    I get them free, work great in my safe.

    Don't waste your money. Go any pet store and buy the cat litter that is 100% crystal silica. Use coffee filters and rubber bands to make up your own packets.

    I tried cat litter but cats kept breaking into the box.

    I know I've read of lacquer which worked great for a long time.
    I also heard of lead foil. Supposedly a good protective wrap.

    My coins are stored in an airtight vacuum in space on a satellite circling the Earth. I'm finding some of my coins have "space toning" . Even this extreme measure isn't good enough.

    Seriously though, I'm also checking for stray rubber bands, paper, extraneous boxes, tape, and making sure the silica gets replenished. Maybe I should put a dehumidifier in the storage room too...

    I don't trust any type of box or safe to be airtight.

    Then lacquer would be your answer.

    Actually, I think air/gases can move thru lacquer.

    Put your coins inside a fruitcake. Nothing can penetrate that!

    Desiccant (typically silica gel) deteriorates rather quickly in humid environments. New, it is light blue in color. Once it has absorbed about 8% of its weight in moisture it changes color, becoming pinkish. It loses its ability to absorb additional moisture at around 40% of its weight and turns white or light green.

    At that point it is useless. It needs to be recharged by heating to dry it or it needs to be replaced.

    The climate where I live is relatively dry. But I use dessicant anyway for insurance. I have several of the type that can be reactivated in an oven. Every 6 - 12 months I toss them in for a few hours.

    And it took you 12 years to come up with that response... ;)

    I think, litter or not, banks will always have to defend better against those cat burglars

    Has anyone put slabs in a cat?

    These are the same silica gel packs I use. I bought an extra set so I can bring a fresh set every time i visit my SD box. Take the "wet" ones home and dry them in the oven and keep swapping them out.

  • If you search through Amazon has pretty good prices on silica. There's all kinds of different sizes for different uses. I put into safe, storage boxes, tubs, even larger rechargeable kind into a couple storage closets.

    I've always purchased my Intercept Shield storage boxes (red, double row for certified coins) from Wayne Herndon

    Best thing out there in my opinion. His prices are very reasonable and he ships SUPER FAST.

    In fact, I just ordered two more for my collection earlier this a.m.

    Good luck!

    Totally agree re Wayne!

    Make sure you throw in some silica gel. A couple of my NGC slabbed Barber dimes turned from blast
    white to gold. I think the gold toning was a result of wrapping the slabs in a canvas bank bag inside
    my box.
