1970 Doubled Die Obverse WDDO-024

Description

Carrying the Wexler designation 1970 1¢ WDDO-024, this doubled die obverse from the Philadelphia Mint adds to the remarkably dense cluster of hub doubling varieties documented on 1970-dated Lincoln Memorial cents. No cross-references have been established in other attribution systems such as CONECA or Coppercoins, meaning this variety is currently tracked exclusively through the Wexler catalog. Hub doubling occurs during die manufacture when a working die requires multiple impressions from the hub to achieve full design depth — a standard part of the production process during this era. If the die or hub shifts between impressions, the resulting die carries permanently doubled design elements that transfer to every coin it strikes. The 1970 Philadelphia cent's extensive DDO roster reflects both the scale of production and the inherent variability in a manufacturing process that relied on precise mechanical alignment across multiple hubbing cycles. WDDO-024 represents a distinct working die from all other numbered varieties in the sequence, identifiable through its unique combination of doubling characteristics, spread direction, and die surface markers. Collectors seeking this variety should note that higher-numbered WDDOs typically exhibit more subtle doubling than the early numbers in the sequence, requiring careful examination under magnification with appropriate lighting angles to reveal the separation between primary and secondary hub impressions.
