1970 Doubled Die Obverse WDDO-016

Description

Approaching the end of Wexler's 1970-P doubled die obverse catalog, WDDO-016 documents another working die from this date that received misaligned hub impressions during the multi-squeeze sinking process. No cross-references to CONECA or Coppercoins have been established, with documentation residing solely within the Wexler system. The sixteenth DDO entry for a single date reflects the extraordinary depth of variety research conducted on 1970 Philadelphia Lincoln cents — a depth surpassing most other dates in the Lincoln Memorial series. This concentration of DDO varieties is a direct consequence of the production conditions: nearly 1.9 billion cents required hundreds of working dies, each sunk through multiple hub impressions where any slight shift embedded permanent doubling. WDDO-016's position near the catalog's end suggests it may represent one of the subtler varieties, following a pattern where the most visible specimens are discovered first and progressively more subtle ones are added as examination techniques improve.
