1986 Atypical Die Clash ADC-1C-1986-01

Description

One of the more visually striking atypical die clashes in the Lincoln Cent series, the ADC-1c-1986-01 from the Philadelphia Mint displays strong evidence of die contact: the obverse shows most of the memorial bays and parts of the building perimeter transferred from the reverse die, along with the letters ON from ONE CENT, while the reverse carries traces of Lincoln's portrait that were subsequently polished over by Mint personnel in an attempt to restore the die to service. The polishing of Lincoln's portrait traces on the reverse indicates this die was not immediately retired after the clash event — instead, the Mint attempted to salvage it by grinding away the transferred obverse design elements, a common cost-saving practice. Additional diagnostic features include linear plating blisters on struck coins and a glossy surface appearance, both of which may result from the die's altered surface texture after polishing or from planchet preparation conditions during the 1986 production run. Cataloged by MadDieClashes, this variety provides a detailed case study in die clash mechanics: the strength of the transferred elements reveals significant die contact force, and the post-clash polishing attempt documents the Mint's practical response to die damage during production.
