2001 Doubled Die Obverse DDO-001

Description

VarietyVista's primary doubled die obverse listing for the 2001 Lincoln Memorial Cent, DDO-001 carries die markers UVC-2475 and DMR-002 and exhibits a light spread on LIBERTY visible as notches on the upper Northwest serifs of the letters. The "notch" manifestation of light doubling is characteristic of varieties where the hub displacement was too small to produce a fully separated secondary image but sufficient to create a visible step or shelf at the serif extremities, where the thin terminal strokes of the letters amplify even minimal offset into a detectable geometric irregularity. The Northwest serif direction indicates the displacement vector pointed in that compass direction — upper-left relative to the coin's orientation — producing the notched effect specifically on the letter serifs that face toward the direction of the hub shift. Three die stages have been documented with distinct die state classifications. Stage A places both obverse and reverse in Early to Mid Die State (EMDS), representing specimens struck while the die surfaces retained most of their original sharpness. Stage B advances to Mid Die State (MDS) on both dies. Stage C reaches Late Die State (LDS) on both dies, where accumulated wear and potential die cracks provide additional diagnostic markers for chronological sorting of specimens. Struck at the Philadelphia Mint in copper-plated zinc (97.5% zinc / 2.5% copper) at 2.5 grams, the 2001 Lincoln Memorial Cent was produced in the billions, yet specimens displaying the DDO-001 notched serifs on LIBERTY represent output from a single die pairing within that enormous production run. The DDO-001 designation as the primary numbered variety confirms this carries the most significant or most prominent obverse doubling among all cataloged 2001 Lincoln Cent doubled die obverse entries.
