Mounting The Celebrate The Century Sheets

How did you mount the U.S. Celebrate the Century sheets?

I just acquired the first 6 sheets 1900-1950 and they are in a wrapper. I put them in sheet protectors but I was wondering how you placed yours in your collection.
If you took them out of the wrapper they came in or used mounts or sheet/page protectors.

I put mine in Showgard 191/229 Mounts. They fit well. Then put them on acid free paper and in a acid free sheet protector.

I use the small acid free clear transparent corner mounts for photo's available from Hobby Lobby and many other sources. They work great for oddball sized sheets/objects like post cards or booklets. These go on 67# card stock and then into an acid free page protector, both of the latter are available from Sam's Club FWIW.

Grampa John I tried that at first and found the stamps would not stay in the corner mounts. I bought a whole package and maybe tried it on 20 sheets. World at War and some others. The sheets were too flexible. So I went to the Acid Free,PVC Free, Archive Safe "Avery" Sheet protectors as well as some Mystic Mounts.

I've tried corner mounts and was not happy with them. I have my Celebrate set in the original wrappers and in sheet protectors. I'm happy with this.

Kathey I have been told by several stampers to take those out of the original wrappers that they will yellow the stamps or do something to them anyway. Several stampers told me this. So I took all of mine out of the original wrapping and put them in Archive Safe, Acid free, PVC free sheet protectors.

Yikes!
You know when you buy packaged stamps from USPS, there's a note that says to remove the stamps.
I ran over to my set and sure enough on the back at the bottom of the package "Package not suitable for philatelic archiving"! I never really looked, so thanks for the heads up.
One more thing to do, 'cause I just might run out of stamps to clean, sort, mount, etc!
Thanks, again! I would be really bummed if these were ruined.

Kathey your welcome. I was just passing on advice I had received. Like you said it would be ashamed to go back in a year or two and find them ruined.
