1990 Typical Die Clash TDC-10C-1990-01

Description

Cataloged by MadDieClashes as TDC-10C-1990-01, this typical die clash on the 1990 Philadelphia-mint Roosevelt dime documents a specific instance where the obverse and reverse dies struck each other without a planchet between them, transferring design elements from one die to the opposing die's surface. On the obverse, the clash mark left by Roosevelt's bottom jaw line is the primary diagnostic — a faint incuse impression of the reverse design transferred onto the obverse die face during the unobstructed die-to-die impact. The placement of these clash marks on the obverse die creates corresponding raised features on subsequently struck coins, appearing as ghost-like traces of reverse design elements superimposed over the obverse portrait area. Die clashes are among the most common die errors in modern U.S. coinage, occurring when a planchet fails to feed into the coining chamber between successive strikes, but documenting specific clash instances by date and mintmark provides valuable data about production conditions and die maintenance practices at individual mint facilities. The 1990 Roosevelt clad dime (copper-nickel over copper core) was produced in large quantities at Philadelphia, and die clashes from this era typically were caught by quality control within a few hundred impressions, after which the dies were either retired or resurfaced. The MadDieClashes catalog systematically records these events, preserving a detailed record of die clash occurrences across all denominations and dates.
