1982 (P) Lincoln Memorial Cent - Zinc Large Date - CU-1C-1982-74 Cud

Description

Following immediately after the Zinc Large Date rim cud at position 73, census entry CU-1C-1982-74 documents a standard interior cud on the same subtype — a die break that extends beyond the peripheral margin into the design field, displacing a portion of the obverse or reverse imagery with a raised, featureless plateau of struck metal. The contrast between consecutive entries alternating between rim and interior classification illustrates the unpredictable nature of die failure geometry: two dies from the same production batch, heat-treated to identical specifications and installed in presses running at comparable tonnage, can fail in fundamentally different ways depending on the location of microscopic metallurgical weaknesses within each die blank. The Zinc Large Date subtype, struck from the 2.5-gram copper-plated zinc planchet with the broader date numerals, represents Philadelphia's post-transition production — the period after the lightweight zinc-core blanks replaced the traditional bronze stock. Collectors identifying this subtype in hand rely primarily on weight, since the visual difference between zinc and bronze can be subtle on well-preserved specimens, though experienced eyes notice the slightly cooler tone of the zinc coating versus the warmer reddish hue of solid copper.
