1971-D Kennedy Half Dollar with Doubled Die Obverse (DDO) error, MS66 grade

The Kennedy Half Dollar was introduced in 1964 to honor President John F. Kennedy following his assassination in 1963. The coin was designed by Chief Engraver Gilroy Roberts (obverse) and Frank Gasparro (reverse). Starting in 1971, the series transitioned from 40% silver to copper-nickel clad composition. The 1971-D issue was minted in Denver, and examples with Doubled Die Obverse errors show doubling in the inscriptions, particularly in 'LIBERTY' and 'IN GOD WE TRUST', making them significantly more valuable than standard strikes. Doubled die varieties are highly sought after by error coin collectors and numismatists who specialize in Kennedy Half Dollars. An MS66 grade represents a premium gem uncirculated specimen with exceptional eye appeal, superior luster, and virtually no distracting marks, placing it among the finest known examples. Such coins appeal to serious collectors and registry set builders who value both the historical significance of the Kennedy series and the rarity of well-preserved error varieties in top-tier condition. The combination of a recognized doubled die error and premium MS66 grade makes this coin particularly desirable in the competitive numismatic market.
