I set off on a project to protect all my Lincoln proofs, every single one of them. Sadly, the majority of Lincoln proofs were improperly stored. This results in the most common effect of hazing, a light, whitish film that forms over the surface. I wanted to be sure my proofs never changed in any way with time, so I'm sharing my project with all of you as you might gain some info.

I follow the reagent grade acetone procedure I previously outlined in this forum.

The airtites are placed in a 2x2 to hold them in my 3-ring binder pages. The entire binder is kept in a super large ziplock bag (available almost anywhere, local grocery has them) with a very large dessicant bag. That bag is stored in a plastic tupperware type container and that is stored in a safe that maintains 60-75F year round.

My next goal is to get ALL my biz strike collection in airtites, as only a few are currently. My local dealer sold me 100 airtites for $75 which I feel is a great deal and worth every Lincoln (pun intended). LOL

Here's how they look in the folder pages:

that is the same system I use and I am very happy with it. I don't use the airtites but I have no haze as of today.

Bad, where do you get the bags of desiccant, and how long does it last before requiring changing?

If the desiccant bag is inside the ziplock and that is inside th Tupperware it will probably be good for a VERY long time. It will take care of the moisture in the air inside the bag pretty quickly and then it will take a long time for any moisture in the air inside the Tupperware to work its way into the bag. And if the desiccant bag is one that is large enough to handle the volume of air inside the Tupperware it will absorb all that and still not need recharging. Then any moisture will have to somehow get inside the Tupperware, and then inside the bag. Through two layers of near airtight protection. So for all practical purposes it will last indefinitely.

Jim, I'm very lucky as far as dessicant. We have a lab instrument that uses 6 large bags, we have to change those out periodically, so I take the used ones home. Conder answered the rest very well.

Thx Bad.

Just do a google search for silica gel. I did a quick check and this site seems to have the best price for bulk about $5 a pound, less in quantity.

http://www.veritemp.com/Products/

A pound will protect about 33 cubic feet. Since your micro environments will be smaller than that you could devde it up into smaller packets. Just have to have some kind of window on the packet s you can see the color change.

You might want to use a rechargeable one. All you have to do is nuke it when you need to dry it out

Here is a link to one site of many that have it

That sounds like a good procedure you've detailed! The only thing I might add is using a glass pipette since some plastics dissolve in acetone, and one wouldn't want that residue on their coins.

Oh btw--I have a source for cent-size "direct fit" Air-Tites @ .29 ea. Not to advertise here, but if you want the distr name, let me know...

The transfer pipets I use are completely inert to acetone.

I guess I didn't get such a good price on the airtites! Please email the supplier for $.29 or just post it here....I'm sure it's not a problem.
