1997-D Doubled Die Reverse WDDR-009

Description

With the catalog number advancing past single digits, WDDR-009 for the 1997 Denver Mint Lincoln Memorial Cent signals that variety researchers have identified a substantial population of doubled die reverses for this date. The ninth documented DDR represents a unique die whose hubbing process introduced measurable misalignment between successive impressions of the master hub into the working die. What makes each WDDR entry distinct is the specific combination of doubling location, spread direction, magnitude, and the die markers that fingerprint the particular die pair. Even when two varieties show doubling on the same elements, differences in spread angle or magnitude — measurable under magnification — confirm they originated from separate dies. The 1997-D cent's copper-plated zinc composition, standard since late 1982, interacted with die surfaces differently than the earlier copper alloy, potentially affecting how doubling appears on struck specimens. Cataloged by the Wexler Team under Wexler Variety ID 1997-D 1c WDDR-009, this variety belongs to the Lincoln Memorial Cents series as Gasparro's reverse approached its fifth decade of production.
