Proof Sets and Mint Sets, how do you store them???

I did the 24 hour test with five Food Saver vacuum sealed bags filled with foam plates, paper napkins, paper towels and a
plastic cup. Submerged the bags in a bucket of water for 24 1/2 hrs. Dried off the bags , opened them up one by one
and all five had NO DAMPNESS at all. The items were as dry as before I sealed them.
The first pic is the item freshly vacuumized.
The middle pic is them submerged in a bucket of water held down with a gallon jug of water.
The bottom is a pic of the items unsealed after 24 hrs. Dry as a desert.

Don't go by the dates in the first two pics. They were stored in my Picasa3 program then exported to My Documents and resized.

 

I bought/read a book a while ago (don't recall where I put it) called "Coin Chemistry". I thought it would tell me how coins toned various ways...but it wasn't about that at all. It was more about how to properly store and care for coins. The one thing that sticks out in my fragile memory is that the author thought very highly of Kointainer products.

 

I was pretty certain that FoodSaver bags were air-tight. I still think I'm right.

thanks zeke!

 

Mikenoodle, this might not be a very scientific test but I thought by sealing five different bags maybe one of them might leak. I would not have been a happy camper. So I too am pleased to find no leakage. I have all my mint, proof, and slabs and valuable coins sealed this way. So far so good.
