So far after 1 full year I have not noticed any quality concerns at all in any of my cased coins.

Or am I worrying for nothing? And overthinking it?

I've never seen a case like that for a single slab. I assume it would be used to house a very expensive slabbed coin. Does the inside of the case smell like rubber or plastic such as PVC? If not, it's probably safe to store a slab. You could always put the slab in a small polyethylene zip lock bag before putting it in the case to give it an extra layer of protection.

No smells of rubber or plastic.

Most single coin holders, which are inert, are okay. Most of the time a coin goes bad because the owner does not store it in place which is climate controlled (heat and humidity), or it's been dipped or otherwise played with, and the coin doctor didn't remove all of the chemicals he used. Over the long term, that probably ruins more collector coins than anything else.

Was just nervous since they are made in China.

I don't know where slab plastic comes from these days. I was thinking of Capital Plastics and Eagle holders from raw coins, tokens and medals. I have found safety flips are oaky too, at least for several years.

TheGoonies1985

I don't know if there is any plastic in the building material of these cases. Does not seem like it. Seems to be all made of metal except for the inner layer.

I don’t get it, how can a smell damage a coin that is already inside a slab? Seems like you guys are worrying for nothing. That’s like saying a “new car smell” will get you into an accident when you’re driving….

Slabs are NOT airtight. Also, if you can smell the plastic, it's giving off fumes or vapors otherwise you wouldn't be able to smell it.

And what would that do to a coin?

Not all slabs are air-tight, particularly older ones. A smell would indicate off-gassing of volatile chemicals which could potentially deposit on a coin in a slab.

Would you be worried about using such cases? I had one coin inside a single case for 2 years that was the longest then sold the coin there was no damage at all the coin looked the same as the day I purchased it.

TheGoonies1985

So to come back to my original post has anyone been using such cases and have you ever experienced any problems such as PVC damage over time?

that being said, you almost answer you own question.

the very short of it is, take as much risk with the amount of value you have in your coin(s). the more valuable, the less risk should be taken. nothing wrong with seeking addition protection but i wouldn't be trying to reinvent the wheel seeing as how fragile coins can be to environmental/physical storage changes. people have had them turn sitting in bank vaults which i presume are quite climate controlled-ish. adding unknown materials to that equation seems like it is asking for disaster.

i'm sure there are probably some tried and true extra storage protection available as it has been discussed MANY times on this forum and using a site such as wizardcoins, a well-known and essentially proven coin caretaker supply provider.

of course you did one of the best things possible, coming here and asking.

make sure they are safe from day 1. you never know what may happen in life that you aren't able to check on your coin hoard and if any problems exist, may be too late before you catch it in time. of course the added fees, risk and turnaround time i doubt will go away any time soon as well. hope it helps.

I purchased mine from Wizardcoins threw Ebay.

That is the dealer I buy them from Wizardcoins.

I am guessing if such a supplier sells them they should be OK.

most likely but you and you alone are responsible for your coins and their storage.

i'm not bending your arm but if you choose to share one of the lovely coins that may find itself entombed in one of these cases, i certainly won't try to stop ya.

I try to not to show my coins to prevent further competition. They are not expensive less than 4k in most cases but simply hard coins to locate. One would be like my icon image not that coin exactly but the same coin in different condition. Thanks for the help.

Since you are buying through an established coin supply vendor, they may have checked the materials out. The fact that you have stored coins already for a couple of years is an indicator the boxes may be stable. You could inquire at Wizard Coins and see if they have done due diligence on the products. I would do that before I purchased such items. Cheers, RickO

I tend to be very risk averse, especially with my "better coins". This means that I ONLY use storage items specifically identified as inert 'and/or' archival. Example

For comparison, see the manufacturer's 'product page' for the box in the OP. It says that it is "sturdy", and "perfect" for keeping coins safe during travel. There is, however, no mention of long-term storage, inert materials, or archival quality.

Like @ricko suggested, some additional research may be required. Perhaps contacting the manufacturer directly would be insightful.

FWIW - I am NOT an expert on this topic. However, as I understand it, 'PVC/plasticizer' is only one of the dangers. In addition to climate factors, there are other corrosive gasses that can potentially impact your coins via tarnishing.

Edited to add a third reference that discusses the impact of packaging on silver jewelry.

It may be very difficult since it was made in China.

Good point.

Sorry for not being more clear. I meant 'Guardhouse/Transline'.

Thanks I will contact them this coming week.

Just checked my messages on my Ebay account this was their reply on my question about PVC:

Hi,

These cases contain no PVC at all.

Thank you.

TheGoonies1985

I guess they are OK (safe) and I will use them moving forward as I have for the past 1-2 years already.

I will still call them and ask about the ''gases'' you guys mentioned. But my guess is these are safe to use. But just to have a clear mind I will get in touch with them.

My guess is Wizard would be well informed about what they buy and offer as to not ruin their reputation.

ricko

@KingOfMorganDollar... Thanks for the information. If they have checked that far, I would think they have investigated thoroughly and deem the containers safe from all outgassing. Cheers, RickO

Will update here about the ''gasses'' once I get a response from Wizard. Will call them this coming week.

CoinHoarder

I DO NOT have the answer to your question.

But, if I do not know for sure about the safety of these containers, I would just store my coins in the PCGS or NGC boxes.

I certainly would not count on a supply vendor spending too much time on determining the long term safety of one of the storage supplies that they sell.

SmEagle1795

I've avoided both of the products listed due to there being an obvious smell to them (as mentioned, this is indicative of some outgassing occurring).

Whether this will hurt coins in 20 years is hard to say but I don't want to take the risk.

Bigtree

I agree with the two comments above. Even though the risk of the coin being affected is small, why take on the risk?

I have a somewhat similar case for five coins that I keep on my desk as a temporary "waystation" - for coins I got recently, or ones I'm about to send out or transfer to long-term storage. Everything else goes in Intercept bags/pouches in my SDB or an Intercept slab box.

Here is the answer I received about gassing:

Hi,

There isn't any known damaging chemicals, but since these have only been around for the past 10 - 15 years, no one has tested them for fifty. Just make sure that coins are always in air tight slabs, certified or otherwise, so if there is any chemical that can cause damage to metal it will be kept away from the coin.

Take care

So now we know there is no PVC materials in these cases what could the other chemicals do to silver coins? The PVC was my main concern.

Corrosive gasses could tarnish them over time. For more details, please see the three references that I supplied earlier.

Thanks. As far as tarnishing them if that should happen no big deal the PVC damage was my main worry.
