1971-D Doubled Die Obverse WDDO-009

Description

Ninth doubled die obverse in the 1971 Denver Kennedy Half Dollar catalog, WDDO-009 rounds out an extensive cluster of hub doubling varieties that collectively document the die manufacturing conditions at the Denver Mint during this transition year. Attributed by the Wexler Team under Wexler Variety ID 1971-D 50-cent WDDO-009, this variety carries unique die markers and doubling characteristics that distinguish it from the eight preceding entries. Nine doubled die obverses for a single date and mint is a substantial count even within the Kennedy Half series, which benefits from a large collector base and systematic die study. The 1971-D was produced in quantities exceeding 302 million pieces, requiring hundreds of individual die pairs throughout the production year. Each die pair represented a fresh opportunity for hub alignment variation, and the statistical likelihood of doubling across such a large die population ensured that multiple examples would be created and eventually documented. Collectors seeking this specific variety must verify die markers against the Wexler reference photographs to confirm the WDDO-009 attribution.
