1964 Proof Kennedy Half Dollar - Doubled Die Obverse WDDO-024

Description

Twenty-fourth among the proof Kennedy Half Dollar doubled die obverses cataloged for 1964, WDDO-024 extends the long list of hub doubling events documented under the Wexler system as 1964 50c Pr WDDO-024. The sheer depth of this DDO family — with numbers reaching into the high twenties and beyond — tells a production story: Philadelphia's die shop manufactured an enormous quantity of obverse proof dies to sustain the 3.95 million proof set production, and each die went through a multi-impression hubbing process where even fractional misalignment between successive hub strikes would create a doubled die. The mathematical probability of misalignment across such a large die population virtually guarantees a significant number of DDO events, which is precisely what the catalog reflects. Kennedy's portrait by Gilroy Roberts, with its fine detail in the hair texture, the sharp serifed LIBERTY, and the motto IN GOD WE TRUST, provides the diagnostic canvas where each unique DDO manifests its individual spread pattern. As a 90% silver proof struck in the last year of that composition for the denomination, the 1964 Kennedy Half Dollar occupies a transitional moment in U.S. coinage history — the Coinage Act of 1965 would eliminate silver from dimes and quarters and reduce it to 40% in half dollars. Attribution of WDDO-024 requires isolating its specific spread direction and intensity from neighboring catalog entries through comparative analysis under controlled magnification.
