The Barber coinage consists of a dime, quarter, and half dollar designed by United States Bureau of the Mint Chief Engraver Charles E. Barber. They were minted between 1892 and 1916, though no half dollars were struck in the final year of the series.

The quarter, formally known as the quarter dollar, is a denomination of currency in the United States valued at 25 cents, representing one-quarter of a dollar. Adorning its obverse is the profile of George Washington, while its reverse design has undergone frequent changes since 1998. Since its initial production in 1796, the quarter dollar has held a significant place in American numismatics, with consistent production since 1831.
