LDB4-1957-016 Die Break
Error
Description
Among the documented die breaks on 1957 Proof Lincoln Wheat Cents, Hardy 57P-4EL+29 stands out as the twenty-ninth segment in an extended lateral break sequence — indicating a die that fractured progressively across multiple striking sessions before retirement. The 4EL+ classification denotes an extended lateral break with additional fracture segments radiating beyond the primary crack path, distinguishing it from simpler face breaks or standard lateral fractures. Segment 29 places this variety deep into the deterioration timeline, meaning the die had already developed twenty-eight prior break segments before this one was recorded. Proof dies at Philadelphia operated under immense pressure, striking each planchet multiple times against polished surfaces to achieve mirror-like fields and frosted devices, and this repeated stress accelerated fracture propagation far beyond what business strike dies experienced. The Cohen attribution remains pending, indicating the variety has not yet been incorporated into that parallel catalog system. Die study specialists pursuing the 1957 Proof die break census prize late-segment varieties for the deterioration narrative they document.
