1942 is a very common date for Mercury dimes. In worn condition their retail value is about 0.18 X the current price of silver; a metal dealer will pay less.
Look on the back of the coin to see if there's a small mint mark letter next to the E in ONE. It may be blank or there may be a D or S. (The W on the front of the coin is the designer's monogram and not a mint mark.)
Numismedia lists the following approximate retail values as of 08/2014:

DISCLAIMER: The retail values quoted are the best available as of the date shown, but may vary significantly due to changes in the precious metals market. Also the wholesale (buying) price of a coin will be less than the selling (retail) price. A reputable coin dealer will be able to give a more accurate valuation based on inspection of the coin.
