What is the worth of a 1931 nickel with bald eagle perched on shield back and man holding hammer front?

There is no 1931 nickel with a bald eagle perched on a shield on the back and a man holding a hammer on the front. The 1931 nickel's reverse features Monticello, the home of Thomas Jefferson. The obverse, or front, of the nickel shows the profile of President Thomas Jefferson.
