I have never seen a holder like this. Is it a coin holder made of mylar plastic or is it something else?  |

It looks more like PVC. One way to tell is by feel. PVC is soft and flexible, Mylar is kind of stiff.

Looks like PVC. Mylar has to be creased to hold a fold, and even then it still wants to reopen; PVC is soft enough to hold a fold without a sharp crease.

OK, I think I will toss it then. A coin I bought was in it. I put a coin in it for a couple of days and when taking it out, the inside felt slimy and thought something was weird. Maybe this is a stamp holder? I know what you mean about mylar not wanting to stay shut. The flips I buy at the coin shop has to be creased and they still pop open.

It is kinda the European version of a vinyl flip. I get them frequently on purchases I make from European dealers. Al the ones I have gotten so far have been made of plasticized PVC.

Don't store coins in these soft plastic holders. I've had an Indian Head penny (1865) and a 1934 German 5 Reich coin develop a green tarnish from the holders... |

Huh, Europeans must have PVC slime on their coins.

Mylar 2x2's have clear thin mylar panels with cardboard stiffening that has a central hole to show the coin.
All of the attributes relating to the coin can be noted on the cardboard.
An ideal way to identify and store World and ancient coins.
Soft PVC has an oily plasticiser to make the PVC soft and pliable. The problem is that the plasticiser can gas out over time, to condense directly onto the coin contained therein.

If its soft and pliable it's probably PVC.

I have had a few of these types of holders over the years, DO NOT STORE your coins in them for any time beyond a few days. I left some Indian Head cents in one of my storage lockers for a couple of years, the coins were literally floating in green juice when I finally got them out. PVC contamination. Just not worth it to even try them out IMO. "Buy the Book Before You Buy the Coin" - Aaron R. Feldman - "And read it" - Me 2013!

Thank you for posting this information, I only had two coins stored in that kind of holder, just tossed them in the garbage.

Hopefully you tossed the holders, not the coins  |
