What is the value of a 1944s us nickel with a shield?

To clear things up - it's "nickel", not "nickle", and the last shield nickels were made in early 1883. A 1944 US nickel carries the familiar portrait of Thomas Jefferson used up till 2004 and a picture of his home Monticello on the back.

These coins are unusual because they don't contain any nickel metal due to wartime shortages. They're made of copper, manganese, and silver. The large letter over the Monticello's dome is the mint mark. Please see the Related Question for more information.
