Who makes the best mint sheet protective pages for for storage in binders / albums? I have about 16 full sheets which have been stored between wax paper and between cardboard for the last 70 or so years. Thanks.
The sheets shown are worth about 50% of face value. So if they were mine (and assuming that there is no significant sentimental value), I would be looking for a safe but inexpensive storage method. Don
For the older, read fragile, sheets I would NOT use a sheet holder with a pocket closed on three sides. I would look for the version closed on two sides left and bottom. That way you lift up the covering plastic lay or remove the pane with minimal stress. You may accidentally split perfs or the entire pane when trying to slide in or out a pane on a three sided closed pocket.
Mint sheet files as suggested by Don contain pockets which are open on two sides.
Lastly, do not store the mint sheet file not a binder with mint sheet pages flat. Keep them vertical like a row of books on a shelf. The binders are fine as is when stood up but, I find it useful to put the mint sheet file into an album dust cover and add enough other stuff, more mint sheet files, stock book, regular book to fill the space to keep the mint sheet file(s) vertical with out sagging.
Edit: Used album dust covers are inexpensive (except for White Ace) but do carry a shipping charge by mail. If you can check with a dealer in person, that save shipping.
Another alternative for preservation is to use mylar sleeves, like the Mylites 2 brand (2 mil thick). These are more often used for holding comic books. They cost about 33 cents per sleeve in quantity (check on ebay, etc.) https://www.egerber.com/catalog_mylites2.htm
But as @studebaker51 advised, the mint sheets you showed are fairly low value. (The 50 x 1c Roosevelt sheet is 50 cents in face value, and the sheet sells for about 25c total - so many people saved them that there is a big oversupply). So it's only worth spending money on holders if you enjoy the preservation process.
Regarding the youtube video: Since paper used to be acidic, collectors studied and warned about the effect of acidic paper on stamps. Now most papers are alkaline. Any info on the effect of alkalinity on stamps? Just because it wasn't studied doesn't mean it doesn't have a destructive effect in long-term usage.
