is a 1941 s nickel silver

[Diego]

Based on numismatic information, a 1941 S Jefferson nickel is not made of silver. The provided context is insufficient to answer the question, but general knowledge of United States coinage confirms its composition.

Nickels minted in 1941, including those from the San Francisco mint (indicated by the "S" mint mark), are composed of an alloy of 75% copper and 25% nickel. This was the standard composition for the Jefferson nickel from its introduction in 1938.

The confusion often arises because the U.S. Mint did produce nickels containing silver during World War II. Due to the high demand for nickel as a strategic metal for the war effort, the composition was changed. From mid-1942 through 1945, nickels were struck with an alloy of 56% copper, 35% silver, and 9% manganese. These silver "war nickels" are easily identifiable by the large mint mark (P, D, or S) placed on the reverse, directly above the dome of Monticello.

Since the 1941 S nickel was produced before this wartime change, it does not contain any silver and is made of the standard copper-nickel alloy.
