Coin Sizes - millimeters

We know its not easy determining what system will work for you.  The following chart provides estimates of popular coinage for your convenience.  As always, please remember to measure your actual coin with a coin caliper to insure that you get the perfect fit in a SAFE air tight coin capsule, page or coin case.  Or alternatively, you could also print our new handy coin template and lay your coin directly on the sheet to get the proper size.

Please also take a look at our new US Coin Reference Chart sorted by Face Value for our Coin Cases.

When you are done, take a look at our wide variety of coin cases and other coin collecting supplies available. 

Coin CalipersAnd if you are an avid coin collector, please pick up one of our coin calipers - in either plastic, brass or a digital version.  You will be glad that you did.

If you are still having difficulty deciding what works for your collection, please feel free to call us at 877-395-7233 and our experienced collectors will be very happy to assist you.
