1966 Doubled Die Obverse DDO-026
Error
Description
Twenty-sixth in the obverse doubled die census for the 1966 Kennedy half dollar — struck in the 40% silver-clad composition unique to the 1965-1970 transitional period — DDO-026 shows light spread on an anatomically diverse set of design features: the chin, eye, ear, and Gilroy Roberts' designer initials GR on the Kennedy portrait. VarietyVista cataloged this die under UVC-100 and DMR-028, recording three die stages with an unusually complete progression: Stage A where both obverse and reverse are confirmed at early die state, Stage B at mid die state (unconfirmed), and Stage C where both obverse and reverse have reached confirmed late die state. The confirmed EDS and LDS endpoints — with only MDS unconfirmed between them — provide bookend documentation of this die's service life, indicating that specimens have been verified from both the beginning and end of the die's production run. The comment "BS" (business strike) distinguishes this from a proof variety, confirming it appeared on circulation-intended strikes. Philadelphia produced all 1966 Kennedy half dollars, with no mint facilities using mintmarks during the 1965-1967 period when the Treasury eliminated marks to discourage hoarding of silver coins during the compositional transition. The light spread on chin, eye, ear, and designer initials clusters the doubling on the portrait's facial features and the small GR monogram near the neck truncation — anatomical areas where Gilroy Roberts' carefully modeled sculptural detail provides contours sensitive to even modest hub displacement. The 40% silver-clad composition (80% silver, 20% copper bonded to a pure copper core) produced different striking characteristics than the preceding 90% silver or subsequent copper-nickel clad issues, potentially affecting how doubling manifests on struck specimens. Collectors should examine the facial features — chin, eye, ear — under 12-15x magnification, looking for secondary contours displaced from the primary portrait modeling.
