1990 Typical Die Clash TDC-1C-1990-03

Description

The third typical die clash cataloged for the 1990 Philadelphia Lincoln Memorial cent, TDC-1C-1990-03 documents another instance where the obverse and reverse dies made contact without a planchet between them. Typical die clashes — as distinguished from the radical MAD clashes that involve severe misalignment — occur when the dies are in or near their normal alignment during the unintended contact, producing transferred design impressions that appear close to their expected mirror positions on the opposing die surface. On the obverse of a clashed Lincoln cent, the Memorial building's roofline, columns, and inscription elements may appear as faint incuse impressions in the field surrounding Lincoln's portrait; on the reverse, Lincoln's shoulder, bowtie, and adjacent lettering may appear as ghostly impressions in the field around the Memorial. Die clash collecting on Lincoln Memorial cents has developed into a specialized pursuit within the broader error coin hobby, with researchers like those at MadDieClashes systematically cataloging each clash event by date, documenting rotation angles, abrasion status, and the specific design elements transferred. Three cataloged typical die clashes for a single date and mint provides comparative material for studying the range of clash characteristics. Struck at the Philadelphia Mint on a copper-plated zinc planchet (97.5% zinc, 2.5% copper) at 2.5 grams and 19mm diameter.
