18mm Ring Fit Coin Holders for US Dimes

To properly care and protect coins keep them in the best possible condition with AirTite capsules. AirTite capsules snap together firmly to form a tight seal, securing your coin for long-term storage. They also keep your coins from coming into contact with your hands. It is best not to touch silver, as the oils from hands can speed up the tarnishing process and leave unwanted fingerprints. Your silver will now be protected, and you will prolong the life of your coins.

Capsules are PVC free, archival safe, and are made from an acrylic plastic with a non-yellowing agent. This process results in a product that is hard, crystal clear, and smooth to the touch. Our capsules are securely packaged, un-assembled, within layers of foam to protect them during shipment.

As there is not a Direct Fit option for every coin in the world, the ring type holders offer a convenient solution to accommodate a variety of coins. We recommend sizing down from your coin's diameter to ensure a proper fit. For example a coin that measures 18.5mm would size down to the 18mm Ring Holder. The inner foam ring will stretch to provide a nice snug fit. Please note, sizing down from the coin's diameter will only apply to Ring Type Holders. This technique will not work for the Direct Fit Holders.

18mm holders

Works great. Excellent quality

Great little cases...

The white inserts seem to fit just a tad bit snugger then the black inserts. Both fit my dimes well. Would order again.

Capsule works well

Capsule works well for gold quarter eagles in terms of width. There is a bit of vertical rattle.

Great product and Great seller

First ordered on Amazon and now ordering directly here -- can't go wrong with the Air-Tite capsules

19mm Air-tite Capsules with Black ring

Great product to protect dimes. Black ring gives great contrast.
