Airtight display case so you can see your coins. Descant are those little bags you see in a lot of electronics packages, they absorb moisture from the air. Traci

 

I understood what those things were, just didn't understand how it fit the thread to this point, sorry.

 

Could you guys show me where you'd buy airtite display cases?

All I could find so far were vinyl albums and storage boxes.

 

I've found that is not so much how much the airtites cost but how much shipping is added to the order... If only needing 10-20 airtites ......shipping at $6.00 or so really adds to the cost....

 

Luis, I built my own from scratch. I will post a picture of it latter, after I get time to photograph. Its very simple if you have the knowledge and the tools. Traci

 

Air-tight vs. Air-Tite Holders -- not Air-tite display cases.

 

It is actually the PVC plasticizers that can become airborne and affect a coin not in direct contact with the PVC. This is prevented by minimizing the amount possible in the air. Any holder that reduces exposure will aid in preventing PVC damage. This includes a stapled 2x2 cardboard holder at the low end and vacuum sealed inert plastic at the high end. However, there may be problems of storage related to all ( yes, even air-tite(tm) and intercept (tm) products.

The Largest problem by far is the collector. Often expensive solutions are utilized, but then they are put away in an environment such as a SDBox for extended periods with out checking for small cracks, punctures, manufacturing defects, and improper installation and closure, and environmental gas factors.

Damage is done by the plasticizers forming chemical reactions on the surface of the coin. A very inexpensive "PVC damage detector" can be made by finding a correct size CD jewel case that will hold a couple of cents, and punch with heated nail held in pliers a few times to give air holes. Then prepare a couple of " sacrificial cents" by taking some BU [ NON VALUABLE POST 1982 COPPER PLATE CENTS] and abrasively clean until you can see the cleaning lines, rinse and dry well, and put into the case and close it. Now, any environmental gases that come into your SDB or other storage case, area, album, etc. etc. will attack this raw copper metal quicker than your "real" coins. Ever so often , check the "detector" and see if they are still bright and shiny, or are become colorful. If severe, reconsider your storage methods. You can use a small silver bullion coin also the same way. I have one in a small hard plastic mini-case, I found some place, that barely holds one cent, but it can be put into an old fashion cardboard album. These detectors are also providing intercept{tm} type protection by reacting with the gases for far less price. For those who wonder about toning environments ( for long term 'natural toning') these detectors also tell you if an old album is outgasing well enough to produce a toning environment. Not advocating this use, but I am sure it occurred to you.

Thanks Jim. I'm glad you found this thread and could explain the airborne PVCs and gases. That's what I was thinking might be a potential problem of coins bound up in a closed space like a safe or SDB when PVC products are in proximity. I like your DIY detector too. I might try that out myself.

 

Spend some bucks and do it right. This is what i use...the aluminium case and you can get the coin boxes that fit the various air-tites.
Its can be kind of pricey, but when your spending 10 bucks and up for a primo Lincoln BU red cent...its worth it.
each tray(box) holds 48 of them.

Couple f questions and thanks for your input!
1) Looks like you used the air-tites with the ring... Correct?
2) What "size" 2x2 cardboard did you use - Half size?

 

They are Cowens PVC-free pages! I put that whole binder into a super large ziplock bag with a couple huge dessicants packs. Then that whole thing goes into a bank deposit box. I know my coins are 100% protected and safe!

 

Yes, I prefer the ring to the direct fit Airtites. I use either half or quarter 2x2's, I like the quarter size a little better, the Airtite fits just right in those.

 

Thanks! :hail:

 

Sorry....I meant to say I like the HALF size 2x2's better! DOH!
