What is the value of 1939 silver Liberty nickel?

Your coin is a familiar Jefferson nickel rather than a Liberty nickel, and it isn't made of silver.

Liberty nickels were made from 1883 to 1912, and popular mythology to the contrary, nearly all US nickels are made of an alloy of copper and nickel, with no silver at all. The only nickels that ever contained silver were minted during WWII.
