A History of the War Nickel

Before World War II, the Jefferson nickel was a staple of American pocket change, instantly recognizable by its familiar design and distinctive metallic feel. These coins were composed of 75% copper and 25% nickel—a balanced mix that gave the nickel both durability and its characteristic silvery appearance. However, as the world was plunged into conflict in the early 1940s, the demands of war quickly reshaped even the most ordinary aspects of daily life, including coinage. Nickel, once just another element in the five-cent piece, was suddenly in high demand for the production of armor plating and other military equipment. Recognizing its importance as a strategic material, the United States government made the decision to conserve nickel for the war effort. In response, Congress authorized a change to the Jefferson nickel’s composition, prompting the U.S. Mint to search for a suitable alternative. After a period of testing and experimentation, the Mint settled on a new alloy: 56% copper, 35% silver, and 9% manganese. This innovative blend not only preserved the coin’s usability in everyday transactions but also ensured that it would continue to function reliably in vending machines and other coin-operated devices across the country.

The introduction of the new wartime alloy was not immediate or universal. The first Jefferson nickels featuring the silver-manganese-copper blend made their debut late in 1942. However, it’s important for collectors and historians alike to remember that not all nickels from that year bear the same composition. Earlier in 1942, both the Philadelphia and Denver mints continued to strike nickels using the traditional copper-nickel alloy, while only later did Philadelphia and San Francisco begin issuing coins with the new wartime formula. As a result, careful examination is required to distinguish true “war nickels” from their more typical counterparts minted in the same year, making these coins all the more intriguing for those passionate about numismatics.

From 1943 to 1945, every U.S. mint produced Jefferson nickels with the special wartime alloy. This change didn’t just keep coins in circulation—it introduced a numismatic milestone. To help distinguish these special wartime nickels, the Mint enlarged the mintmark and placed it above Monticello’s dome. The Philadelphia “P” made its debut on a U.S. coin with this issue. The prominent ‘P’ on the 1945 nickel not only marked its origin but also told the story of wartime ingenuity and the changing face of American coinage.

The 1945-P FS-801 Doubled Die Reverse

Beyond composition, the Jefferson nickel’s story includes fascinating mint errors and notable varieties sought after by collectors.

The Philadelphia Mint produced over 119 million nickels in 1945, but only a fraction display the famous FS-801 doubled die—one of the most sought-after varieties.

The FS-801 variety stands among the most important doubled dies in the Jefferson Nickel series. PCGS identifies three major doubled-die issues in the classic series: the 1939 Doubled Die Reverse, the 1943 Doubled Die Obverse, and the 1945 Doubled Die. Collectors can identify the 1945-P FS-801 most readily by examining the lettering below Monticello. NGC catalogs the variety as FS-801, CONECA DDR-001, and VarietyPlus VP-001. Older references identify it as FS-030.

Strong doubling appears on MONTICELLO and FIVE CENTS. Examples also show doubling through portions of UNITED STATES OF AMERICA. The separation becomes especially prominent toward the right side of the lower reverse. Heritage has described particularly strong spread on the final letters of MONTICELLO and CENTS. Unlike minor strike anomalies, these dramatic doubled dies resulted from a flaw in the die itself—making them highly collectible.
