1966 Doubled Die Reverse DDR-002

Description

A Special Mint Set variety, the 1966 Kennedy Half Dollar DDR-002 displays a light spread on STATES OF AMERICA and the stars positioned beneath those letters on Frank Gasparro's reverse. Cataloged by VarietyVista as UVC-092 with die marriage reference DMR-020, the obverse is paired with DDO-018, making this a dual variety coin where both obverse and reverse dies carry hub doubling. Three die states track the die's progression: Stage A at early-to-mid die state (EMDS) pairs the reverse with the DDO-018 obverse also at EMDS, while Stages B and C at mid and late die state remain unconfirmed. The 1966 Kennedy Half Dollar was produced exclusively in Special Mint Set format — no proof sets were issued from 1965 through 1967 — in 40% silver-clad composition during the transition from 90% silver. The SMS production process creates coins with enhanced finish quality that falls between circulation strike and proof, providing favorable conditions for detecting light hub doubling. The dual variety status — DDR-002 reverse paired with DDO-018 obverse — makes this a particularly appealing specimen for Kennedy Half collectors, as it documents hub doubling anomalies on both dies used for a single die marriage during the SMS era.
