2020 (P) Lincoln Shield Cent - TYC, DCL, STT 001

Description

Carrying the compound designation TYC, DCL, STT 001, this 2020 Philadelphia Lincoln Shield Cent exhibits three simultaneously occurring error types: a typical die clash, a die clash, and a strike through — a convergence of multiple error mechanisms on a single die pair that reflects both a clash event between the obverse and reverse dies and a separate strike-through event where foreign material intervened between the die and planchet during striking. The obverse shows a particularly appealing die clash of UNUM and other parts of the shield reverse design, transferred as incuse ghost impressions where the reverse die's raised elements impacted the obverse die surface when the dies came together without a planchet between them. This type of clash is sometimes described colloquially as producing a "mirror image" of the opposing die's design, though the transfer is seldom complete and typically affects only the highest-relief portions of the design that make first contact during the misfire. The cross-reference note indicates this variety was not yet listed on MadDieClashes at the time of documentation, suggesting it was identified independently of the primary die clash reference database. The distinction between "typical die clash" (TYC) and "die clash" (DCL) in the compound designation reflects the cataloging system's differentiation between standard clash patterns that appear regularly on Lincoln Cent dies and more distinctive or unusual clash configurations. Struck in copper-plated zinc at 2.5 grams, the 2020-P Lincoln Shield Cent features Lyndall Bass's Union Shield reverse introduced in 2010. Collectors examining this variety should look for incuse reverse design elements ghosted onto the obverse surface, particularly around Lincoln's bust and in the surrounding fields.
