Mercury dimes are very popular ten-cent pieces produced by the United States Mint from 1916 to 1945. This dime is composed of 90 percent silver and 10 percent copper. The coin contains a total of just over .072 troy ounces of silver.

The Mercury Dime is also commonly referred to as the Winged Liberty Head Dime and was designed by Adolph Weinman. The coin got its common name from its reverse depiction of a young Liberty which was confused with the Roman god Mercury.
