    Howdy! I knew I'd find some friends here!

    I looked at your profile and didn't see your name, but it's always good to hear from a happy customer.....even if I don't know who you are! Thanks for the referrals too. Feel free to email me any time.... sales@air-tites.com

    I like air-tites a lot and can't think of a better way to store valuable raw coins and bullion coins. I also have a few of the ones with the loop on the rim in red. I put Christmas design silver rounds in them and hang them on the tree. Clever product.

    I keep all my raw coins (that are worth anything) In Air-tite holders, And I wouldn't have any way else. THank you for such a great product.

    Howdy Marty - Welcome to the Forum !!

    Sorry, but I have to disagree with your comment. But before I continue let me say that I am a huge fan of Air-Tite holders - have been for years. I recommend them almost exclusively on a regular basis.

    But as for their being actually airtight - let me recommend that you try a little test. Take any air-tite - close it up, completely. Place about 1 inch of water ( no more because you want a fair test - no pressure ) in a small bowl. Place the closed air-tite in the water with any small object on it to hold it down in the water. Leave it there for about an hour.

    Remove the air-tite and dry the outside completely with a paper towel or tissue. You will still see water droplets after drying - on the inside.

    Now it's much easier to make something watertight than it is airtight because water is thicker and heavier than air. So if it's not watertight - it's not airtight either.

    I've known this for years - I tested my first Air-Tite in the same way. Tested another brand new one just tonight - same result.

    Not one to be generally contentious GDJMSP and I gotta say I trust your opinion as a rule more than most anyone when it comes to coin-related facts and fancy. But just possibly could another force have been at work during your experiment? I am referring to the fact that water will condense from air as it is cooled. Could the immersion of the Air-Tite into the water bath have cooled the air inside the Air-Tite to the point that moisture formed on the inside? Just a thought.

    And a good thought to have - but I had it to. So I've made sure the water was luke warm - room temp. They leak - plain and simple. Anyone can try the test for themselves. No need to take my word for it.

    I’m not sure what the water pressure is at a few inches depth, and I’m not motivated enough to drag out my physics book to figure it out, but I’m thinking that maybe when the holder is submerged in water there’s a sufficient pressure differential between the water outside and the air inside to result in the water finding a way in.

    Normally the holder would contain some air at the same pressure as the air outside, and there wouldn’t be a pressure differential to force the outside air to “squeeze” its way through the holder pieces to the inside.

    Maybe.

    Oh man! I've been here less than 24 hours and ya'll are already making me tired! ;)

    As I mentioned in my "introduce yourself" post last night, we are not the manufacturer of Air-Tite capsules..... we are one of the largest resellers in the U.S. So from the manufacturing perspective I really can't elaborate on the difference between "water tight" and "air tight", and I'm not educated enough to even venture a hypothesis explaining why something that is touted as "air tight" may not be "water tight".

    However, I do know this for a fact: I have HUNDREDS of coins of all types in my personal collection that are encased in Air-Tites and many have been in the same capsule for years. I have only noticed a couple of Silver Eagles that have toned slightly, and it may be that those particular capsules didn't seal off perfectly (perhaps GDJMSP tested a capsule that was less than perfect, who knows?) or it could be that all Air-Tites will allow water inside if left submerged for an extended period.

    So, in defense of Air-Tite holders as a whole, I have never seen any literature that touts them as being "water tight", "water proof", "radiation proof", "acid proof", "idiot proof", etc. They are touted as "air tight" only. I would guess that we've sold a couple million capsules in the past few years, and I have NEVER had anyone call or write complaining that they were unhappy with the quality or the results they've experienced with these capsules.

    I have a $500 Leupold Vari-X III scope on my deer rifle that is GUARANTEED to be waterproof, but I still wouldn't submerge it in a bucket of water for any amount of time just to find out. So you have to keep things in perspective guys. We're talking about a 50 cent piece of acrylic that I would not be afraid to use to protect a $100,000 coin.

    Does this apply to Size A for use with dimes, pennies, and nickles. Also do you have to manually center the coin or does the case do that as well.

    Hello Morgan,

    If you use the direct fit model, the capsules are sized for specific coins. For example: A18 - Dime, A19 - Cent, A21 - Nickel, A24 - Quarter, T30 - Half Dollar, H38 - Morgan, Peace, Ike Dollars, H39 - Silver Rounds, H40.6 - Silver Eagle.

    The number simply represents the inside diameter (approximately) of that particular capsule. So, to answer your question, the capsules center the coins perfectly themselves. The ring type holders are basically the same, and the foam ring centers the coin inside the capsule.

    Hope this helps you. Feel free to email me directly if you need further assistance.

    Hey Marty, I've been wanting to ask this question and you seem to be the guy to ask. What is the ring made of in the ring type Air-Tites?

    I'm not complaining either Marty - I've used them for years and will continue to do so. They are in my opinion the best coin holder on the market today. I'm not knocking the product in any way.

    You say they are touted to be airtight - by whom ? I've never seen an ad or anything else that actually says so - other than what the name implies. Who is the manufacturer by the way ? I've never been able to find out. I'd like to ask them if the product is actually airtight.

    Very few manufactured items in this world are actually airtight - it's not all that easy to do. Slabs form PCGS, ANACS, ICG - they aren't airtight either. NGC has an airtight slab now - but only for the past year or so. None of the old ones are. And no other coin holder, manufactured by anybody, is airtight either. So please don't take my comments the wrong way.

    Illya - the rings are produced from cross linked polyethylene (trade name "Volara"), which is totally inert.

    Marty:

    You have just made another friend.

    I just finished sending off an order to your company on-line.

    I look forward to receiving the product.

    :) :)

    I will be ordering from Marty soon too. Ive read before that there is no actual coin holder that is airtite (before NGC changed slabs)
    Did PCGS mention anything about changing to airtite slabs anytime soon?
