1776-1976 United States Bicentennial Quarter with potential Double Die Obverse (DDO) error, copper-nickel clad composition

The 1776-1976 Bicentennial Quarter was issued to commemorate the 200th anniversary of American independence. The reverse features a Colonial drummer designed by Jack L. Ahr, replacing the traditional eagle design for this special year. Over 1.6 billion of these quarters were minted across Philadelphia, Denver, and San Francisco facilities, making them widely available. Double Die Obverse (DDO) errors occur during the minting process when the die strikes the planchet multiple times with slight misalignment, creating a doubling effect on design elements such as lettering or the date. These error coins are highly sought after by numismatists and error coin collectors who specialize in mint varieties and production anomalies. Authenticated DDO Bicentennial quarters can command significant premiums over standard examples, particularly when the doubling is prominent and clearly visible on key design elements like 'LIBERTY' or the dual dates '1776-1976'. The value depends heavily on the strength of the doubling and professional authentication by services like PCGS or NGC.
