Hi everyone, I've got a question on binders. I have been storing all my coins in 2x2's, and the 2x2's are in 2x2 pages. All so far are coin safe. Does it make a difference what the material the binder I put these pages in is made of? I am now using the binders in the link. They are made of a hard plastic type material. Is this safe to use long term? Will the binder material penetrate through the coin safe page, and then penetrate through the 2x2? Or does it not make a difference long term? Thanks. *** Moved by Staff to a more appropriate forum. ***http://www.staples.com/1-Staples-Be...oduct_648819 |

Binders are not the potential problem, it is the pages. For long term storage, they should be NON PVC, archival quality.
The plasticiser (which makes the clear pages pliable and soft), can gas out and get to the coins inside the Mylar of the 2x2 holders over a period of years. The result is that the coins will darken and if left, will eventually become black.

As an aside, I am wondering if the self adhesive 2x2 would be a better option as they are sealed air tight instead of the staple type 2x2s which are not air tight and would be more susceptible to the effects in the atmosphere around the coin  |

I think the self adhesive 2x2's may be better because of being air tight, but I am left to thinking:
If the plasticiser can gas out of the pages, then the Mylar, over the longer term of years, must be somewhat porous.
Something like an osmotic membrane.

This is my take on it as well thats why I paid the extra bucks for the non pvc archive type folders. The self adheisive are just an extra precaution, It dosnt hurt to double up on prevention  |

That one looks nice. I have been zipping my binders up in big ziplock bags to keep out dust now.. And humidity..

If you're using a binder up to its limit it helps if it's a D-ring. Don't skimp on quality because they keep the pages parallel and don't make a curvy fold the way O-ring binders do.
For pages I was using the "blue margin" pages which a tad cheaper than the "brass ringed" pages. Lately, though, I switched to the brass ringed pages because they're stronger (awesome for big silver coins) and don't have that PVC smell. Now the only thing I need are smaller 2x2 flips and the pages that hold an extra 4-5 coins each.

One more thing on binders.
DON'T store them on end. Lay them flat.
The weight of the coins over time will cause either the pages to deform and tear, or damage the rings in the binder.
Also slip cases are a good idea for your binders as this will let to stack a couple on top.
Cheers
Peter
