US and Foreign Coin Diameters

When measuring a coin or medallion not listed, it is best to drop down a ring size when it measures a fraction of .8mm or less.  For example, a 35.7mm coin uses a 35mm Air-Tite, a 35.9mm coin uses a 36mm Air-Tite.

Coins shown in RED have Ring Type and Direct Fit Air-Tites available.

There's a fast, easy way to choose the right AirTites holder for your coins! Just download and print out our handy Ring Diameter Gauge, then lay your coins right over the template.
