1984 Atypical Die Clash ADC-10C-1984-01

Description

Strong die clashing on both obverse and reverse distinguishes ADC-10c-1984-01, an atypical die clash on the 1984 Philadelphia Roosevelt Dime. Unlike typical die clashes where dies strike each other in their normal aligned position, atypical clashes involve rotational or lateral displacement, producing transferred design impressions in unexpected locations on the die face. John R. Sinnock's Roosevelt portrait and torch reverse, in continuous production since 1946, generated their share of die clash events across nearly four decades of clad coinage by 1984. Philadelphia's dime production in the mid-1980s was substantial, running at high speeds on modern presses where planchet feed failures — the primary cause of die-to-die contact — occurred with statistical regularity across millions of strikes. The "ADC" prefix in the MadDieClashes classification system specifically denotes atypical clashes, separating them from the "TDC" (typical die clash) category, and the systematic designation 10c-1984-01 identifies this as the first cataloged atypical clash for the 1984 dime. Cataloged by MadDieClashes, this variety demonstrates the specialized focus of die clash research, where the geometry of the transferred impressions provides forensic evidence of the precise misalignment between dies at the moment of their unintended contact. The strength of the clashing on both sides suggests the dies made firm contact without a planchet intervening.
