Guardhouse - 2x2 Double Pocket Flips - Unplasticized Vinyl

I store my binders flat also, and because of what you mentioned, the weight of the coins makes it slide around and fall over anyways if stood on end.

At some point I'll get more organized and do a binder per country or something like that or at least continent or region or something, but for now Canada takes up the most space followed by Panama and then probably Bahamas.

Ok.. Good to know. Can anyone else confirm this?

My storage is more for organizing my metal detecting finds. I'm not worried about the effects on my silver coins. If they tarnish over time I will just clean them up with baking soda as I did the first day I detected them.

 

I don't get it.

 

I use the Guardhouse flips for my CRH and Coinstar finds. So far I have them in three coin albums. I like the flips and have been using them since 2013 with no issues - earlier flips cracked after awhile.

 

OK, I'll do some research, but off the top of my head... PVC is usually a stiff, brittle plastic, but materials called plasticizers can be added to the stock resin before it is made into sheets so they can be flexed. That material is often dioctylphthalate which is a non-volatile oily material which disrupts the polymer chains and lets them slip past one another. Now, some plastics are naturally flexible, such as PET (Polyester) and PE (Polyethylene). PET seems to be the choice for flexible coin products.

I bought a bunch of cardboard/mylar holders and pages from Guardhouse - very good list prices. That is their in-house brand - Transline was at the top of the invoice. To conserve space, using 1.5x1.5's for quarters, dimes, nickels, cents, and 2x2's for larger. On top of that they were offering a 10% discount, plus free shipping with orders of $10 or more (made those purchases on August & September 2020). They also sell products from other manufacturers, but those discounts applied only to their in-house brand.

 

The confusion over exactly how safe the “unplasticized” PVC flips might or might not be keeps me from using them. It’s frustrating because I have a bunch of low-value coins for which the 1.5 inch version would be ideal.

 

Any thoughts on Low-density polyethylene (LDPE) - a thermoplastic made from the monomer ethylene. Commonly used in the food industry. I've been using these for some time now. I'd say 5 years and see no adverse effects. I simply make sleeves from the little bags by trimming them and this also eliminates any friction between the coin and container while sliding in/out of the flips. I also use them zip style as intended.
