LDB4-1957-019 Die Break

Description

Nineteenth interior die break on the 1957 Proof Lincoln Wheat Cent, LDB4-1957-019 was documented on September 10, 2016, as part of the sustained research effort that has cataloged dozens of die fracture varieties on this single proof date. Cross-referenced as Cohen Pending and Hardy 57P-4FL+ in the dual classification system, the Cohen number awaits formal assignment while the Hardy system has provided a preliminary designation. The LDB4 prefix identifies this as a class 4 interior die break — distinguished from rim cuds by the fracture's location within the die face rather than at the edge. The 1957 Proof cent was produced exclusively at the Philadelphia Mint as part of proof sets, and the concentration of die break varieties on this date has made it a focal point for collectors specializing in die failure varieties. Proof striking involves higher pressures and more deliberate coin ejection than circulation strike production, creating distinct stress patterns in the die steel that can promote fracture initiation at different locations than those typically seen on circulation dies. The Wheat Cent design was in its forty-eighth year by 1957, with only one more year of production remaining before the Memorial Cent reverse debuted in 1959. Cataloged by Cuds on Coins, this variety continues the comprehensive documentation of 1957 Proof die failures.
