Most 1 ounce (oz) silver coins, like the American Silver Eagle, have a diameter of 40.6 millimeters (1.598 inches) and a thickness of 2.98 millimeters (0.1173 inches).
However, some 1 oz silver coins and rounds may have slightly different dimensions depending on their origin and manufacturer. For instance:
- Some generic 1oz silver rounds have a diameter of 39 mm and a thickness of 3.1mm.
- The Canadian Silver Maple Leaf coin has a diameter of 38mm and a thickness of 3.29mm.
The differences in size can be attributed to variations in minting processes and the fact that silver is less dense than gold or platinum, so a 1 oz silver coin will take up more space than a 1 oz gold or platinum coin.
