Are round plastic air tight holders good for storage?
I removed my JFK halves from the. Whitman and placed into air tights because in a short period of time, like 2 months one of the proofs started to tone. I also have some of the silica gel packs. Do I keep those near the air tights? In the box? Or outside of the box? The box is metal. Thanks for any advice and I was not clear let me know.

You should not see any problems with any proof kept in an AirTite. The silica gel packs should be kept inside the same container that holds your coins. In your case, inside the metal box.
I will add that I do have my proofs in Dansco albums and have had no problems. A big part of it is how and where you store the albums. A coin in an AirTite is a bit more forgiving of the environment than a Dansco (or Whitman, for neither are air tight and can be affected by the environment). That being said, you can never be too careful.

One thing to remember about Airtites ... once they are sealed, they don't recommend opening them. You can re-use them, but the company doesn't consider them "air tight" anymore. I have several toned pieces that I wanted to "arrest" the toning. They've been in airtites for a couple of years now and show no changes.

Anything you use for coin storage is OK as long as no air, gasses, moiture, etc. can get to the coins. As noted Albums and Folders are far from air tight. Even the most expensive ones are not air tight. Albums are really made so you can observe or change coins easily and in such a situation, they must be made with loose tolerances.
I keep all my Albums in Zip Lock Plastic Bags with as much air pushed out as possible. So far in many, many years I've had no problems with toning, corroding, tarnishing, etc.
Regardless the amount and type of storage may well depend on the amount of time you are thinking of for long term.

currently, for really sealing the coin, it's the vacuum sealed laminate film for the proof silver coins, which can cost one around US$5,000 for the vacuum chamber + film cost. On the inexpensive alternative, airtites are great to segregate the coin from the earth's atmosphere. But then it's really not air tight, care against air and surface contaminants should be made during the coin sealing process - and yes, dont open it again  |

Round Airtights are nice for the coin but there are available Airtights Slab type that resembles PCGS slabs. They are perfect to store them on boxes. Most of my favorite coins is being stored this way : (pls see the picture below)  |
