1967 Kennedy Half Dollar with DDO (Doubled Die Obverse), 40% silver-clad composition, United States Mint

The Kennedy Half Dollar was introduced in 1964 to honor President John F. Kennedy following his assassination in November 1963. The 1967 issue marked a transition period, as it was the first year the coin was struck in a 40% silver-clad composition rather than the 90% silver used in 1964. A Doubled Die Obverse (DDO) is a minting error that occurs when the die strikes the coin blank multiple times in slightly different positions, creating a doubling effect on design elements such as lettering, dates, or facial features. This error significantly increases the coin's value and desirability among collectors. Kennedy Half Dollars with DDO varieties are highly prized by error coin collectors and numismatists who specialize in die varieties. The 1967 DDO Kennedy Half Dollar appeals to collectors of mint errors, Kennedy Half Dollar specialists, and those building comprehensive error coin collections. Such varieties are valued for their rarity, historical significance, and the technical insight they provide into the minting process. Error coins like this represent fascinating anomalies in American coinage and command premium prices in the numismatic market.
