The history of U.S. Federal Contract Coinage dates back to periods when the U.S. Mint faced challenges in meeting coin production demands. During the California Gold Rush in the mid-19th century, private mints were contracted to produce coins to support the booming economy. In the 20th century, particularly during World War II, the Mint outsourced coin production to private companies to conserve metals for the war effort. This practice resurfaced in later years for special commemorative issues and to address production shortfalls, reflecting a longstanding partnership between the government and private sector in U.S. coinage history.

The history of U.S. Half Cents began in 1793 when they were first minted by the Philadelphia Mint, making them one of the earliest coin denominations produced by the United States. These small copper coins were created to facilitate everyday transactions and were in circulation until 1857. Throughout their minting, half cents underwent several design changes, including the Liberty Cap, Draped Bust, and Classic Head varieties. Despite their practical use, their production ceased due to the growing unpopularity and the advent of more efficient coinage systems. Today, half cents are valued by collectors for their historical significance and rarity.
