World Coin Size Chart

It is very difficult to judge the size of a coin based only on a photo. While U.S. coin buyers generally are aware of U.S. coin sizes, the same does not apply to world coins. I will post sizes in my World Coins descriptions. To help you visualize the size of a world coin, here are approximate diameters of current U.S. coins for comparison, in millimeters:
• 3 Cent Silver 14mm
• ½ Dime (Liberty Seated) 15mm
• Roosevelt Dime 18mm
• Indian/Lincoln Cent 19mm
• Jefferson Nickel 21mm
• Quarter 24mm
• ½ Dollar (Walking Liberty) 29mm
• $20 St. Gaudens 34mm
• Morgan/Peace Dollar 38mm
