2010 Doubled Die Reverse WDDR-001

Description

Cataloged by the Wexler Team as WDDR-001 on the 2010 Lincoln Shield Cent, this doubled die reverse presents extra thickness on the designer's initials LB — the monogram of Lyndall Bass, who sculpted the Union Shield reverse introduced in 2010. A diagnostic notch appears on the lower right of the L, providing a quick attribution checkpoint visible under moderate magnification. Die markers on the obverse include distinctive trail-like extensions running southwest from the bottom of each date digit, while the reverse carries a die crack along the top left of the shield and a die chip on the top right of the shield north of the second U in PLURIBUS. Cross-referenced as Coppercoins 2010P-1DR-002, this variety is independently documented in two major attribution databases. The Lincoln Shield Cent is struck on copper-plated zinc planchets weighing 2.5 grams with a diameter of 19.05 mm, continuing the composition introduced in 1982. The Union Shield reverse replaced the Lincoln Memorial design that had served since 1959, making 2010 the inaugural year of a new era for the cent denomination. The concentration of doubling on the designer's initials rather than on the larger shield elements suggests a localized hub displacement that exceeded the visibility threshold only on the fine letterforms of the LB monogram, where even small offset produces proportionally significant thickening relative to the stroke width. The southwest-trailing date digits on the obverse serve as die-specific fingerprints that confirm attribution independently of the reverse doubling itself.
