Coin Storage

I think I've figured out how slabs get scratched...

So does this mean that the products purchased from the mint should be taken out of the cardboard boxes that they come from and separated from any other paper?

 

I've seen it recommended here before the coin is to be removed from the box and the packaging saved away from the coins.

 

I've been using Intercept Shield products for years , and they have significantly reduced any toning . rysherms , how do you feel about IS products . Also have you read Weimer Whites book on Coin Chemistry ? Do you agree or disagree with him ?

 

i havent read the book,

this is how i feel...please see what other readers of this book think...

and for those who are too lazy to read it, here is a common response to the book:

This book was an expensive advertisement for Intercept Shield, a series of products meant to protect silver coins from corrosion.

 

CoinArmour is a scam. there is a CHEMICAL difference between toning and tarnishing. anyone who argues that last part is uninformed or just "going with the incorrect flow of what is accepted in their circle of collector friends"

if you dont like the truth, or are a closet employee of Intercept/Coin Armour, I have nothing left to say to you, you do not even understand your product, chemistry, and are trying to scam money out of people. i despise you and your business practices.

 

I don't generally believe that a box will cause problems, as I've stored coins in boxes for decades. I do know that plastic containers release constituents that destroy Silver coins over an extended period. It took some time to determine why my BU Silver coins, stored as paper wrapped rolls in tubs turned black in my safes. I saved some relatively undamaged, for storage in ammunition cans with desiccants.

 

no offense bud, but this is the kind of misinformation that people are being poisoned with. PVC plastic is bad for coins. Polystyrene plastic is COMPLETELY inert to silver, AND IS THE PREFERRED MATERIAL TO STORE A COIN IN, IN FACT, THE BETTER VERSION OF AIRTITES ARE PVC, EVEN AIRTITES ARE ACRYLIC. This is how a company like Coin Armour markets to knowledgeable victims, by not knowing chemistry and building a product on a false premise.

 

It's your prerogative to store as you'd like, and your BOLD LETTERS, will not change my 60+ years experience of storing 90% Silver coins. I'm just conveying the knowledge gained by storing in "plastics" of the past. I didn't state the exact material of construction, as I really didn't investigate, and you may or may not be correct.

I suspect there are few in this venue who've stored the quantity/quality/duration of Silver coins as I. I still have hundreds of filled boxes with 2" x 2" sealed coins from the early fifties that appear to this old man as when I stapled them in place. I also have at least a 6 figure sum of severely "toned" 90% coins, having been stored in close proximity to "plastics" that created an irreversible condition.

Please reconsider your rant. I believe, know, from 40+ years of scientific design experience that a proper metal container, as I recommended, surpasses plastic for extended storage.

 

Umm. Polystyrene is a poor barrier to both water and oxygen. Why would such a product be "the preferred material to store a coin in" by any measure?

 

rysherms , you haven't read the book , then say you feel the same way about the book as someone you quote . How can you have an opinion for or against something you haven't read . I would think someone as educated as you say you are , would want to read it for yourself , or have no comment on it either way .

 

Sorry I meant polypropylene...that was my error

 

The first thing I said was I haven't read it...and I find it reasonably suspicious that by just googling it turns up an opinion that it is an advertisement for Intercept....if you want to give your money away by all means go for it

 

I couldn't agree more...start by "pouring out" some of your misinformation so that you can let science fill that space. Great analogy btw.

 

Just a personal educated observation!! From my perspective/understanding, knowing the human fallibility of us all, I'd WAGER that Dougs published comments are less diluted by untruths than most, and respectfully, yours.

Please consider constructive supported civil retorts.

JMHO, Rich

 

Actually I did not say what you said. I said that a layer of silver oxide or a layer of silver sulfide would give the same appearance depending on the thickness of the layer. The color is caused by reflection/refraction of light that can be interfered with constructively or destructively depending on the thickness of the film. Why do soap bubbles show some of the rainbow toning we see on some silver coins? The soap material is white or transparent, so the color here is a similar phenomenon. Now, if we go further, either process of forming silver sulfide of silver oxide is an oxidation of the silver. If the silver oxide gets thicker, the coin will dull and be kind of lusterless, while if the silver sulfide gets thicker, we have more of a chance of the coin turning black as in classical tarnish. I try not to get too dogmatic about chemical stuff because guys that have been around coins as much as someone like Doug have actually seen a bunch of stuff it would be very hard for me to intelectuallize. It's like trying to instruct a chem lab using a manual where a very knowledgeable chemist has written the experiments, but obviously hasn't done them because in practice, lots of thing are quite different than theory. I don't know anything about the Coin Armour having never used it and haven't read the literature.

 

rysherms , All my best coins are kept in a safe deposit box , now I know these were made for storage of paper and not coins . The best coins , slabbed , are kept in IS Slab boxes . Now most of the unboxed coins have gotten darker , but the ones kept in the IS boxes have not noticeably changed much at all . Could you explain this .

 

absolutely, you have reduced the amount of air flow....SAME AS A ZIPLOCK BAG WOULD DO MY MAN!

 

That makes sense , but a part I left out is , I also have coins in IS 2X2s and they haven't noticeably changed either . Now the IS 2X2s are in the same compartment as the slabs and probably let more air in than a slabbed coin . Why haven't they darkened like the slabs .
