What is the value of a 1921 Mercury dime?

1921 is one of the rarer years for Mercury dimes. 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 (The W on the front of the coin is the designer's monogram and not a mint mark.)
