What is the value of a 1946 silver US nickel?

Please don't assume that because a coin is old it must contain silver. All nickels except the famous "war nickels" from 1942-45 are made of the same metal, an alloy of copper and nickel. Silver was used in dimes, quarters, and halves up to 1964 but the lowly nickel wasn't worth enough to contain any silver even back then.

No such (US) coin exists. 35% Silver nickels were only made from 1942-1945 with a large mintmark over the Monticello. All nickels before or since have been made out of 25% nickel and 75% copper.
