1971-S Doubled Die Obverse WDDO-005

Description

The Wexler files list this variety as 1971-S 50¢ Pr WDDO-005, positioning it as the fifth cataloged doubled die obverse for the remarkably variety-rich 1971-S proof Kennedy half dollar. Produced at the San Francisco Mint in copper-nickel clad composition (75% copper, 25% nickel outer layers bonded to a pure copper core), this proof coin weighs 11.34 grams with a 30.6 mm diameter. The proof production process at San Francisco involved individual handling of polished planchets struck by specially prepared dies, creating coins with mirror-like fields and sharply defined design elements. This superior strike quality means that hub doubling characteristics are displayed with exceptional clarity on proof specimens compared to business strikes of the same denomination. WDDO-005 falls within the early-to-middle range of the extensive series of doubled die obverse varieties known for 1971-S proof half dollars, which collectively number more than a dozen distinct listings. Each variety originates from a separate working die that received imperfect hubbing, and identification requires matching the specific direction, magnitude, and location of the doubling along with confirming die markers unique to that particular die. Gilroy Roberts' Kennedy obverse design offers numerous reference points for doubling detection — the hair texture above the ear, the letters of LIBERTY and IN GOD WE TRUST, the date numerals, and the truncation of the bust all serve as potential pickup points. Collectors should consult the Wexler reference images when attributing any 1971-S proof half dollar doubled die to ensure accurate classification among the many similar varieties.
