1991 Doubled Die Reverse WDDR-002

Description

Cross-referenced as Coppercoins 1991P-1DR-003, the second doubled die reverse for the 1991 Philadelphia Lincoln Memorial cent documents a die whose misaligned hubbing impression produced diagnostically distinct doubling from the eight other varieties cataloged for this date. The Coppercoins cross-reference places this variety within an independent attribution framework alongside the Wexler system, giving collectors two reference paths for confirmation. With nine doubled die reverses now identified for 1991-P cents alone, the date represents one of the more prolific years for reverse hubbing errors in the Lincoln Memorial series — a pattern that speaks to the mechanical tolerances and production pressures at the Philadelphia Mint during this period. Attributors working through the 1991 Philadelphia doubled die reverse sequence should compare diagnostic die markers carefully, as the large number of varieties for this single date means that multiple dies exhibit doubling on similar design elements, making marker-based identification essential for accurate classification. Struck at Philadelphia on copper-plated zinc planchets composed of 97.5% zinc and 2.5% copper, weighing 2.5 grams and measuring 19mm.
