Mercury dimes, more formally known as Winged Liberty Head dimes, minted from 1916 to 1945 is a popular series of U.S. coins to collect. If the coin shows signs of wear on it due to being used in business transactions, it considered "circulated." If it was never used, then it is considered "uncirculated." The photos below show examples of both conditions.

The History of the Mercury Dime

In 1916 the Treasury Department conducted a design competition to replace the stoic design of the Barber dime that had been minted since 1892. On March 3, 1916, Mint Dir. Robert W. Woolley announced that he selected Adolph A. Weinman's design as the winner. His design featured Lady Liberty wearing a close-fitting Phrygian capped with wings to symbolize freedom of thought. Most people miss took this as the Roman god Mercury and began calling at the Mercury dime. Its proper name is the "Winged Liberty Head".

The reverse of the coin features a Roman fasces as a symbol of power and strength with an olive branch to symbolize peace. The Mint produced the first coins in late 1916 with the United States entering World War I in the following year.

The Market for Mercury Dimes

Mercury dimes are a popular series to collect amongst coin collectors. Demand is relatively stable for coins in uncirculated condition. For lower-grade circulated coins, a majority of its value is based upon the coin's silver melt value. Each Mercury dime contains almost 1/10 of an ounce of silver (0.0723 oz. exactly). As of this writing, silver is currently selling for almost $16 per troy ounce. Therefore, each dime contains approximately $1.20 worth of silver. If you want top dollar for your coins, you need to sort them and organize them so the dealer can quickly see what you have.

In fact, coin dealers and numismatists can tell right away if a coin has been cleaned. They will then classify your coin is damaged which will greatly reduce its value.
