CU-1C-1952D-02R Cud

Description

Second documented reverse cud on a 1952 Denver Mint Lincoln Wheat Cent, this major die break formed when a rim section of the reverse die fractured and separated entirely. The resulting cavity in the die face filled with planchet metal under striking pressure, producing the distinctive raised featureless mass that characterizes a cud error. Cataloged by Cuds on Coins with the cross-reference CU-1C-1952D-02R, this variety documents die rim failure on a post-war era cent from the Denver Mint. The 1952-D date saw substantial production as the Korean War era economy demanded large quantities of circulating coinage. Victor David Brenner's wheat ears reverse was in its forty-third year of production, and the die steel that carried this familiar design endured thousands of striking cycles before mechanical fatigue caused the rim fracture that produced this cud. Die rim failures cluster in areas where stress concentrations are highest — typically at points where the rim transitions into design elements or where the rim itself carries the thinnest cross-section. Two reverse cuds from the 1952-D date indicate that at least two separate reverse dies experienced rim failure during that year's Denver Mint cent production run, each fracturing at a different point along the rim to produce distinct cud varieties.
