The story behind the coin
The Civil War made small change disappear. As the war dragged on, Americans hoarded anything with metal value — gold, silver, even copper-nickel cents — and what was left in pockets was a mess of grimy paper "fractional currency," some of it worth as little as three cents. People hated the flimsy notes. The Mint hated them too.
Into that gap stepped Joseph Wharton, an industrialist who controlled most of the nickel mining in the United States. Wharton had product to sell and the ear of Congress. He pushed hard for coins made of nickel — and the heavier the coin, the more nickel each one would consume. His lobbying helped shape the Coinage Act of May 16, 1866, which authorized a new five-cent piece: five grams of metal, 75% copper and 25% nickel. The "nickel" was born, named for the minority metal that made it stand out from the silver coins it replaced.
It also solved a different problem. With no silver half dimes circulating, the country needed a hard, durable five-cent coin that anyone would accept — one worth far less as metal than as money, so no one would melt it. The new nickel fit exactly.
