1776-1976 D Bicentennial Quarter with DDO (Doubled Die Obverse) error, United States Mint

The 1776-1976 Bicentennial Quarter was minted to commemorate the 200th anniversary of American independence. The reverse design features a colonial drummer and a victory torch encircled by thirteen stars, replacing the traditional eagle design. Over 1.6 billion Bicentennial quarters were produced across three mint facilities, making them widely available to collectors and the general public. Doubled die obverse errors occur during the die-making process when the design is impressed twice onto the die in slightly different positions, creating visible doubling on the struck coins. Bicentennial quarters with DDO errors are highly sought after by error coin collectors and numismatists who specialize in mint varieties. These error coins command significant premiums over standard circulation strikes due to their rarity and the technical interest they generate among specialists. The DDO variety is particularly appealing to collectors who focus on die varieties and manufacturing anomalies, as these coins represent fascinating examples of the minting process and add significant value to any error coin collection.
