Hello,

I am interested in buying acouple holders for my currency. What would provide the most protection? I've seen "air tight" holders for coins, are there any for notes? I've heard of some chemicals in the plastics, with PVC, or acids, would I have to worry about those? Thanks!

I always use Polyethylene terephthalate (PET) sleeves - Some people call PET "Mylar", but Mylar is a brand name of a special type of PET, Biaxially-oriented polyethylene terephthalate (boPET). The brand name I use is SafGard, from E&T Kointainer Company, the same folks who make KoinTains and SaFlips. I store the sleeved notes in red currency boxes available from many suppliers.

The sleeves are nice for protection from handling, but doesn't really offer much protection from mis-handling.

I purchased a BCW "Currency Slab" plastic holder from online, and it's quite nice. $8 or so, if I recall, but I wanted something heavier-duty to hold my 81-A K-*.

The box and who I give access the the box provides a great deal from protection from handling.

The BCW Currency Slab is made from polystyrene, which according to this excellent article from Daggarjon is a safe material for archival storage of notes:

The important thing when selecting holders is to buy ones made from the right materials - ask the supplier exactly what it is made of - if he doesn't know, shop elsewhere. Safe materials include polyester, polyethylene (food grade), polystyrene, polypropylene & Plexiglas. PVC, whether it is plasticized or not is not acceptable nor is acetate.

The currency slab is four times the cost of the PET sleeves ($1.57 each for quantity 100), and significantly bulkier. For me, size becomes a significant factor when one has a large number of notes - One box of PET sleeves is about 200 notes, and 200 notes in polystyrene slabs is going to require a whole lot more space for storage.

But, sure, if you have a dozen or a few dozen notes, you may find the currency slabs work just fine.

You must have missed this quote from the nice lady at the Smithsonian:

What are the best kind? Where would be a good place to get them?

NetJohn

Clay, I was giving the OP options. Perhaps he wanted something "tougher" than a standard sleeve? I understand the bulk issue all too well.

Options are a good thing - That's why I ended my last posting with, "you may find the currency slabs work just fine." So, whatever your preference, know what material the currency holder, slab, or sleeve is made from. These materials have been classified as fine for archival storage:

• Polyester - Example: SuperSafe or holders made from Prolar Polyester
• Polyethylene (food grade) - This includes Polyethylene terephthalate (PET), Example: SafGard. Also includes "Mylar" or other biaxially-oriented polyethylene terephthalate polymers. Example: Frame-A-Coin Currency Holders, PCGS Currency Holders are "Mylar D" (See: PCGS Currency Holders "Take the Heat")
  
• Polystyrene - Example: BCW Currency Slabs
• Polypropylene - Example: UltraPro Banknote Holding Ring Binder Display Pages
• Plexiglas which is a trade name for Poly(methyl methacrylate) (PMMA). It is sold under many trade names, including Policril, Plexiglas, Gavrieli, Vitroflex, Limacryl, R-Cast, Per-Clax, Perspex, Plazcryl, Acrylex, Acrylite, Acrylplast, Altuglas, Polycast, Oroglass, Optix and Lucite and is commonly called acrylic glass, simply acrylic, perspex or plexiglas. So, "hard acrylic" holders should be ok. Example: Collector Safe, Capital Plastics Currency Holders, Image Guard Currency Holders

I would be suspicious of anything generically called "plastic", "acetate", "vinyl", or "PVC" (even if the PVC contains no plasticizers or stearates) holders. Sometimes, though, with a little research, you may find the "hard plastic" currency holder is made of acrylic or polystyrene, which should be fine.

If you have raw notes & want to buy holders made from the same as PCGS or PMG holders uses what is a good type to buy ?
I have fractionals in currency Wallets in my safety deposit box.

mpcusa

Mylar-D by dupont, Per that great article!! I will do some research
And find out who stocks them!

mpcusa

You almost have to be a chemist to figure all of this out, But its
Great information that,s for sure!

Hi Rusty, I agree,every time I think I understand it,someone else contradicts the post . My local coin & stamp shop in Brooklyn says their "UN-plasticized Currency Holders are safe for storage in a safe or Safety Deposit box but they don't know the chemical components of the holder...Daaaah ? As they say in B'klyn forgetaboutit...gofigure ?

Hey Bob,

You really have to be your own advocate here! When it comes to protecting
Your valuables, Here,s a quick example, When i was in High School i was kind
Of a Motor head and i guess i still am, Being the proud owner of both a
1969 Yenko Camaro 427 @ 450Hp and a 1987 Grand National Turbo-6 @ 600Hp
But in High School i did have a 1970 Challenger 440 @ 375Hp

Now back to the story i lived in Fountain Valley, Ca at the time and we had
A local speed shop in Costa Mesa, Ca a couple of towns over the name
Of the place was called "Super Shops" But we all called it "Stupid Shops"
Because if you didn,t know what you wanted they wouldnt be able to
Provide any answers for you!
Moral of the story know what you want, And know more about it then them..Lol
