1964 (D) Lincoln Memorial Cent - LDB4-1964D-001 BIE Die Break

Description

Cross-referenced as Cohen NL and Hardy 64D-4SCM-NL (cataloged 10/05/2023), the LDB4-1964D-001 BIE Die Break documents a specimen of the distinctive BIE die break phenomenon that is unique to the Lincoln cent series. A BIE die break occurs when a die crack or die chip develops between the letters B and E of LIBERTY on the obverse, creating a raised vertical line that resembles the letter "I" — making LIBERTY appear to read "BLIBERTY" at first glance. The phenomenon results from the close spacing of the B and E in the LIBERTY inscription on Lincoln cent dies, which creates a narrow web of die steel between the two letters that is particularly susceptible to cracking under the repeated stress of striking. When this web fractures, the crack fills with metal during the next strike, producing the characteristic raised "I" shape. The Cohen and Hardy cross-references connect this variety to two independent attribution systems, providing collectors with multiple reference points for verification. Struck on a 95% copper and 5% zinc planchet weighing 3.11 grams at 19.05 mm diameter.
