what are nickels made of before 1942

[Chavez]

It's a fascinating piece of American history that the composition of the nickel has been remarkably consistent for most of its existence. Before the pivotal year of 1942, the U.S. nickel had a trusted and established formula that collectors and historians know well. From its introduction way back in 1866, every nickel was minted from a durable alloy of 75% copper and 25% nickel.

The year 1942 is such an important cutoff because it marks the dramatic shift in production necessitated by World War II. Nickel became a vital strategic material for the war effort, essential for things like armor plating. To conserve this precious metal, the U.S. Mint was forced to change the coin's composition for a temporary period. This led to the creation of the famous "Wartime Nickels" from 1942 to 1945, which were made with an alloy containing silver, manganese, and copper.

So, when you consider the classic American nickel that circulated for over three-quarters of a century before the war, you should envision that iconic 75% copper and 25% nickel blend. This reliable and long-standing composition is what truly defines the vast majority of nickels in history, setting them apart from the unique, silver-bearing emergency issues of the war years.
