From 1796 to 1837, dimes were composed of 89.24 percent silver and 10.76 percent copper, the value of which required the coins to be physically very small to prevent their intrinsic value being worth more than face value. Thus dimes are made small and thin. The silver percentage was increased to 90.0 percent with the introduction of the Seated Liberty dime; the use of a richer alloy was offset by reducing the diameter from 18.8 millimeters (0.740 inch) to its current figure of 17.9 millimeters (0.705 inch).
