I wish to store my gold in mint tubes, then those mint tubes in small pelican waterproof / dust resistant cases. I understand PVC is bad, however these cases are made from polycarbonate ( hard plastic ) with the bottom lined with Thermoplastic Rubber as this also acts as an O - ring. Should I be concerned with the Thermoplastic Rubber bottom for long term storage if the coins aren't in direct contact with the material? This Rubber / plastic hybrid is what keeps the container dust free apparently. Here is the case I'm buying https://www.bhphotovideo.com/c/produ...icro_Case.html Here is the manufacturer's specifications of the different materials used http://www.pelican.com/us/en/product/watertight-protector-hard-cases/micro-case/standard/1060/ " ThermoPlastic Rubber TPR is best described a material which has both the characteristics of rubber and plastic. Typical applications are the hard rubber/plastic soles on many shoes or the the rubber/plastic material used on hane tool grips " All information is appreciated, I'm assuming it will be fine since the coins would be in mint tubes / small containers, and then placed inside this and not in direct contact with the TPR, and it is the perfect fit. However I simply cannot find any information regarding TPRs and coin storage.
It's not necessary, I enjoy the aesthetics plus it's dustproof. I've already gone ahead and purchased the case, I'll just line the inside with a microfiber and keep the TPR in so it stays dustproof and water tight. Can't hurt, plus I use government issued mint tubes so the case is really just for keeping everything together. I'm not a numismatic guy, I'm just a gold guy, all my gold is 24K anyway, so unless it was literally gold on PVC bare, it won't spoil anything.
My main reasoning was it fits the shorter mint tubes vertically and the longer ones horizontally, so you can store quite a bit of gold in a small amount of space. I just never heard of TPR in regards to gold storage, but I don't think it will matter since it's not like I will carelessly be throwing the coins in there.
*Case is able to be submerged under 1 meter of water for up to 30 minutes in accordance with IP67 testing parameters This seems senseless. I could see it for other (reactive) precious metals, but it doesn't sound like it would be of much help if you lived in a flood zone. Chris
I don't think these are really the intention of these cases - they're more for camera and electronic gear. We use a case like this for our backup drives at work to be taken off-site for storage.
A case is a case, I can fill it with CDs, hard drives, gold, bullets. Personally I have a foam pelican I keep my Sebenza knives in, this one will replace my Apmex cardboard welcome box I've had for awhile.
Yes I agree, flooding isn't really my concern, it's just easy to contain the mint tubes, then lock it up in a safe. I guess I was curious if any other people used pelican cases for PMs and their experience, but I've done enough due diligence at this point it's fine.
As far as I know gold is gold. Unless you have proofs or Pre-33 numismatic coins you essentially have a gob of gold and storing it should not be much of an issue. I use air-tites for mine and even that is overkill.
Thermoplastic Rubber - TPR - is for the most part an inert material. But if exposed to ultraviolet radiation or direct sunlight it can degrade considerably. If it did, that could very well be bad for the coins. The other materials used in the cases you ask about seem to be just fine. But understand this, even though these cases may be watertight, they are not airtight. And air is the primary enemy of all coins. So while using these cases may help with your coin storage issues, they are not going to solve all problems. In fact you would probably be just as well off using Tupperware containers, and for a lot less money.
Lemme put it this way - any sealed container made of inert materials will help. And pretty much all of them will help equally, meaning one is not better than the other. At least not in terms of protecting coins from the air. This is because we simply do not have airtight containers. That is because pretty much all plastics are air-permeable. What that means is the seal used on the container is irrelevant because the air can and will go right through the face of the plastic itself. The benefit of sealed containers is that it slows down the air flow, and less air getting to the coins is a good thing. My primary point is this. You can spend a lot of money on containers trying to protect your coins. But the expensive options aren't going to do any more good than the least expensive options.
Gold will NOT be affected by PVC... unless you are storing it near Aqua Regia (nitric acid and hydrochloric acid), nothing will affect gold......worry more about security.
Bags are inert, but not air tight. Don't believe me? Put something square in one, and close the zipper almost all the way, then suck all the air out so the bag conforms to the shape. You can finish the seal while still sucking and have an almost perfect conformation. A few hours later, there will be more air in there.
I found this storage system on line for my gold 1 OZ and 1/10 OZ coins Its a stacker with air-tites, looks and works really well, if your interested Just PM me and i will give you all the info.
