What Years Did U.S. Nickels Have Silver?

United States nickels hold a unique place in coinage history, particularly a series produced during a specific period. These five-cent coins underwent a significant transformation in their metallic composition. This change was a temporary measure.

Years of Silver Nickel Production

U.S. nickels contained silver from 1942 through 1945. This four-year span marks the only time in American coinage that nickels included precious metal. Not all 1942 nickels contain silver, as the composition change occurred partway through that year. Early 1942 nickels maintained their traditional composition, while those produced later in the year, along with all nickels from 1943, 1944, and 1945, included silver.

1942 nickels from the Philadelphia Mint without a mint mark are not silver. However, 1942 nickels from Philadelphia, Denver, or San Francisco with a large mint mark located above Monticello on the reverse side are indeed silver. The San Francisco Mint exclusively produced silver nickels in 1942.

How to Identify Silver Nickels

Identifying silver nickels, often called “war nickels,” is straightforward. All nickels containing silver feature a large mint mark placed directly above the dome of Monticello on the coin’s reverse side. This placement is the most reliable indicator of a silver nickel.

The mint marks found in this position are “P” for Philadelphia, “D” for Denver, or “S” for San Francisco. While some silver nickels might exhibit a slightly different color, the presence and location of this large mint mark remain the definitive way to confirm silver content.

The Reason for Silver Nickels

The temporary inclusion of silver in U.S. nickels stemmed directly from World War II. As the nation mobilized for the war effort, strategic metals like nickel and copper were needed for military production. Nickel was used for manufacturing armor plating, artillery, and other military equipment.

To conserve these valuable resources for wartime needs, the U.S. government mandated a change in the five-cent coin’s composition. This adjustment ensured a steady supply of nickel and copper for defense industries, redirecting them from coinage to weaponry. The decision also aimed to maintain the coin’s functionality, ensuring it would still be accepted by vending machines.

The Metal Content of Silver Nickels

The “silver” nickels produced during the war years had a unique metallic composition. Each of these coins consists of 35% silver, 56% copper, and 9% manganese. This formulation differed significantly from the standard nickel composition, which comprised 75% copper and 25% nickel.

Manganese was incorporated into the alloy as a substitute for the nickel that was removed. This was done to maintain the coin’s overall weight and electrical properties, allowing it to function correctly in coin-operated devices. The change was temporary, and the traditional copper-nickel alloy was reinstated for nickels after the war concluded in 1945.
