1960 Doubled Die Obverse WDDO-011
Error
Description
Struck as part of the 1960 proof production at the Philadelphia Mint, WDDO-011 exhibits a Class IV spread to the northwest on LIBERTY and IN GOD WE TRUST on the Proof Large Date Lincoln Memorial cent. Class IV doubling — an offset or tilted spread in a single direction — creates a distinctive shadow effect along one side of the affected letters, and the northwestward displacement on this variety means the secondary impression trails below and to the right of the primary design elements. Because proof dies were typically limited to approximately 3,000 impressions before retirement, the total population of WDDO-011 is inherently constrained. The obverse carries four parallel die scratches running from southwest to northeast in the hair to the left of the ear, serving as the principal die diagnostic. On the reverse, a die scratch runs from south-southwest to north-northeast at the top of the 5th Memorial bay, and a vertical die scratch occupies the lower two-thirds of the 10th bay. Cross-referenced as CONECA 7-O-II+V and Coppercoins 1960P-1DO-007P, this variety is cataloged by the Wexler Team as 1960 1¢ Pr WDDO-011.
