Only the war years of 1942-1945 have silver. All Jefferson Nickels from 1938 to mid-1942 and 1946 to date are made of 75% copper and 25% nickel.
That's a silver war nickel from WWII, which contains 35% silver. It's worth about $2.
No such coin exists. All 1942-D nickels are made out of the standard 75% copper 25% nickel. Only 1942-S and 1942-P nickels were struck out of the "war nickel" alloy of 35% silver. A 1942-D nickel is worth about 7 cents if circulated and a couple of bucks if in better shape.

For most dates, none. US nickels made from 1866 to mid-1942 and from 1946 to the present are made of a copper-nickel alloy, not silver. From mid-1942 to 1945 nickels did contain a small amount of silver because nickel metal was needed for the war effort. Those "war nickels" are the ONLY ones that have any silver in them.
The coin has no silver in it. Only the "War Nickels" from 1942 to 1945 had any silver.
