LDB4-1956-002D Die Break

Description

Second die break variety documented on the 1956 Proof Lincoln Wheat Cent, LDB4-1956-002D carries cross-references to Cohen 56-B613 with a cataloging date of May 28, 2016 by Cuds on Coins. The "D" suffix in the catalog code may indicate a specific die break classification within the LDB4 system, distinguishing this break's characteristics from the primary LDB4-1956-002 entry. Philadelphia produced 669,384 proof sets in 1956, a substantial increase over 1941's 15,412 but still modest compared to the multi-million proof set mintages that would characterize the 1960s. The Cohen 56-B613 cross-reference integrates this variety into the comprehensive Lincoln Cent proof die break catalog maintained by Cohen, whose numbering system provides a parallel attribution framework alongside the Cuds on Coins LDB4 system. The 1956 proof cent occupies a late position in the Wheat Cent proof series — with only 1957 and 1958 proofs following before the Memorial reverse transition in 1959, making 1956 one of the final three proof dates carrying Victor David Brenner's iconic wheat ear reverse. Proof die breaks develop when striking pressure, despite being carefully controlled, exceeds the die steel's fracture threshold at localized stress concentration points. The dual cross-reference system (LDB4 and Cohen) reflects the active research community documenting proof die break varieties across the Lincoln Cent series, with multiple attribution frameworks tracking the same physical varieties.
