How much is an 1943 half dollar with walking liberty and upside down eagle on back worth?

The 1943 half dollar with the "walking liberty" design on the front and the upside down eagle on the back is not a real coin. The U.S. Mint did not produce any half dollars with this design in 1943 or any other year. The walking liberty design was used for the half dollar coin from 1916 to 1947, but the reverse design featured an eagle facing the viewer's right, not upside down.
