LDB4-1957-006 BIE Die Break
Error
Description
Among the earliest documented BIE die breaks for the prolific 1957 Philadelphia Mint Wheat Cent, this sixth entry at Hardy position 4 carries confirmed cross-references in both major BIE cataloging systems: Cohen 57-B442 and Hardy 57P-4EL+. The dual listing in both the Cohen and Hardy indices indicates that this variety was independently verified by both reference systems — a level of confirmation that not all BIE varieties achieve, particularly those with "Pending" Cohen status. The Cohen designation 57-B442 places it within a sequential numbering system that encompasses all die break varieties for the 1957 date, while Hardy 57P-4EL+ provides positional specificity within the LIBERTY area. BIE die breaks form through progressive die deterioration: as a die accumulates strikes during production, stress cracks develop in the fields between letters where the die metal is thinnest. The narrow spaces between the uppercase letters of LIBERTY are particularly vulnerable because the tall, closely spaced letters create stress risers in the die steel. When a crack opens in this zone and extends enough to create a gap, struck metal fills the void to produce a raised vertical element on the coin — the telltale "I" between existing letters. Cataloged on July 21, 2015, by Cuds on Coins, this variety contributes to the comprehensive documentation of die failure patterns on what has become the most intensively studied date in BIE die break numismatics. Collectors pursuing complete 1957-P BIE sets face a substantial challenge given the sheer number of documented varieties.
