What is the value of a 1952 silver dollar with a George Washington front and liberty back?

The only thing made by the U.S. Mint in 1952 George Washington on it is the quarter. You may have been thinking of the Booker T. Washington / George W. Carver Commemorative Half Dollar, but that's not George Washington on the front, and there's no Liberty on the reverse. So I have to believe you have something that was not made at the U.S. Mint. Please provide more information in this question's discussion area, providing as detailed a description of what's on each side as you can.
