There is Air-Title and many generics that look just the same. There is Kointains which I have never seen, just head about that they're used in the Smithsonian. I think that's it. Does anyone know if the Kointains capsules would fit in the CAPS Albums?
On the back of the airtite package tells you what letter CAPS page to use for what ever millimeter airtite you are using for your coin...click on pic to enlarge it.
I was assembling an album of ATB quarters in capsules from the US Mint. About 3/4 way through the mint changed capsules and they no longer fit in the album. If I remember correctly they changed twice. I had to but a batch of Airtites and swap them out to finish.
The thing is that the Airtite and Kointains have exactly the same dimensions. At least for the quarters at 24.3 mm. I’m ordering just a few of each to see what I like the best. The Kointains is slightly dome-like so when put into the albums, the pages may not close flush. I’ll update this post when I can.
Yeah, interior dimensions are the same. BUT - exterior dimensions are very, very different ! Air-Tite capsules are much, much larger than Kointains. I don't even know if anybody even makes an album that Kointains will fit in. Somebody might, but if they do I'm not aware of it. edit - I would add one more thing. Once you put a coin in a Kiontain capsule it can be very difficult, sometimes very, very difficult, to get that coin out of that capsule - without damaging the coin !
I use CAPS pages for my toned Canadian, 50 cents, 25 cents, dimes, and cents. Airtites they work great...
Which do people prefer? The Air-Tite with or without the ring inserts? What are the inserts made of? Assuming that one buys the proper size capsule, do the coins rattle around without the insert? What is the likelihood of the surface of the coin coming in contact with the capsule and getting abraded? I have some nicely toned coins and some "frosty" coins that I want to put in capsules, rather than cardboard/mylar flips. I'm trying to decide between Kointains and Air-Tites. I don't really like the visual appearance of the ring insert, but would use it if it really helps protect the coin from movement and abrasion. @GDJMSP comment about getting coins out of Kointain capsules concerns me some, but isn't necessarily a deal breaker, if they actually do the best job of protecting the coin.
The capsules that come from the US Mint vary in dimensions. The mint must use the lowest bidder. They changed twice during the ATB series. I had to take some out of the mint capsules and put them in CAPS capsules. I had to break many of them to get the coins out. That is dangerous for your eyes, fingers and the coin.
The answer will typically depend on one's philosophy on the matter. In other words, what's more important to somebody, looks, or practicality ? Looks of course depends on one's taste, it's a chocolate and vanilla choice in other words. Whereas practicality leaves out such considerations and is based on physical attributes alone. An inert material, can't think of the name off the top of my head but being an inert material is really all that matters. They can, it's possible in other words but typically unlikely. To fully understand the situation a couple of things need to be explained. While the coins and the holders are manufactured to close tolerances tiny differences in diameter are rather common. This is especially true with older coins, and the older the coin the greater the likelihood its diameter will vary slightly. And slightly is all it takes for the fit to be either too tight or too lose. And one is just as bad as the other. Too lose means the coin can move inside the holder, too tight means once you get the coin inside the holder, ever getting it back out of the holder becomes beyond difficult. This is where the importance of the ring insert comes into play for the insert completely, 100% negates any size differences. The ring inserts are made of a flexible material, and sized so that no matter if the coin, or the holder, is a tiny bit big or a tiny bit small, that the coin will be held tightly and securely in place every single time. And, if one collects hammered coinage then the ring inserts become imperative because the diameter of hammered coinage can be all over the map. But there is always a holder and insert size that when used in conjunction will work and securely hold the coin. If the coin can move at all inside the holder then wear will be imparted to the coin. That much is a given.
It sounds like you are partial to the inserts for the best coin protection. I thought the capsules would be somewhat concave on their inner surface to avoid any contact with the face of the coin. In other words, I thought that even if the coin moved a little, only the edge and rim could contact the inner surface of the capsule. I am referring to mint state coins with no rim wear. What is your opinion of cardboard/mylar flips. If one uses the appropriate size and staples them properly, are they okay for toned and "frosty" coins?
Limited experience, but I think they are very similar to airtites in terms of dimensions (inside and outside). Check their website - they might list the dimensions.
I have a few Jefferson's in these. You can easily photo thru them, they don't slide on the coin, for the most part they are airtite. https://www.wizardcoinsupply.com/products/kointains/ Here are a couple of photos. Kind of a protective little bubble.
