Description

Designated by the Wexler Team as 1971-S 50¢ Pr WDDO-011, this doubled die obverse is one of numerous hub doubling varieties documented on the 1971-S proof Kennedy half dollar. The San Francisco Mint produced this coin in copper-nickel clad composition, weighing 11.34 grams at 30.6 mm diameter, with the distinctive proof finish achieved through multiple strikes on polished planchets using chrome-plated dies. The WDDO-011 designation places this among the middle range of cataloged obverse doubled dies for this date, which collectively represent one of the richest concentrations of doubled die varieties found on any single coin date in the half dollar denomination. Hub doubling on proof coins is particularly noteworthy because the mirror-like fields and sharp device edges of proof strikes can make doubling characteristics more visible than on business strikes, where die wear and circulation contact may obscure subtle varieties. The Kennedy half dollar obverse features Gilroy Roberts' left-facing portrait with IN GOD WE TRUST along the lower rim and LIBERTY arching across the top, elements that commonly serve as pickup points for doubled die detection. Frank Gasparro's reverse presents the Presidential Seal with its heraldic eagle. Collectors attributing this variety should carefully compare their specimen against the Wexler reference images, as the multiple WDDO varieties for 1971-S proof half dollars can share similar general characteristics while differing in the specific direction, magnitude, and location of the doubling spread.
