21mm Ring Fit Coin Holders for US Nickels

Protect your investment with the best coin capsules on the market. AirTite capsules snap together firmly to form a tight seal enclosing the ring and securing your coin for long term storage.

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. The foam rings are made from an inert polyethylene. These rings provide an extra barrier against air contamination, secures the coin in the holder, and provides and attractive border. The rings are designed to stretch to accommodate foreign coins that may have an odd diameter.

Our capsules are securely hand-packaged, un-assembled, within layers of foam to protect them during shipment. The rings are placed into the bottom halves of the capsules for quick use, excluding the 250 Pack quantities. Packs of 250 sell as a full case of capsules with the rings on the side.
