1970-D Doubled Die Obverse WDDO-033

Description

Final entry in the current Wexler DDO sequence for the 1970-D Lincoln Memorial cent, WDDO-033 carries a cross-reference connection to WDDO-032 — submitted by Keith Christenson — that links these two varieties as related discoveries within the 1970-D doubled die census. The nature of their relationship, whether shared die preparation characteristics, similar doubling patterns, or markers suggesting dies from the same production batch, rewards close comparative study of both varieties side by side. Thirty-three confirmed doubled die obverses from a single date and mintmark places the 1970-D cent in rarefied territory within U.S. numismatics, representing one of the largest DDO concentrations ever documented for any coin. This extraordinary count reflects both the Denver Mint's massive cent production requirements in 1970 and the systematic research efforts of variety specialists who have combed through the date's output over more than five decades. Each WDDO number represents a physically unique working die that entered production carrying hub doubling artifacts, struck some quantity of cents, and was eventually retired — thirty-three separate die preparation errors preserved in copper across millions of coins released into circulation. For the cherry-picker working through 1970-D cents, WDDO-033 stands as evidence that the discovery pipeline for this date may not yet be exhausted: if thirty-three dies have been confirmed, the statistical likelihood of additional undocumented DDO dies lurking in unsearched hoards or rolls remains meaningful. Examination of the date area under magnification, with particular attention to the horizontal bar of the 7, remains the most efficient initial screening technique.
