SKH-10c-1964D-01 Spiked Head

Description

Uniquely notable for its cross-reference to an unlisted repunched mintmark, SKH-10c-1964D-01 documents both a spiked head die clash variety and a concurrent RPM on the same 1964 Denver Mint Roosevelt Silver Dime. The notation "Unlisted RPM" indicates that while the repunched mintmark has been observed on coins from this die pair, it has not yet been formally cataloged in the standard RPM reference guides — a status that could change as researchers examine additional specimens. The combination of a spiked head and an RPM on a single die pair makes this variety doubly attributable: the spiked head results from a die clash event where the reverse design transferred into the obverse die, while the RPM reflects a separate production step where the D mintmark was punched into the reverse die more than once without perfect alignment. The 1964-D Roosevelt Dime holds special significance as the final regular-issue 90% silver dime — beginning in 1965, dimes were struck in copper-nickel clad composition as the rising price of silver forced the government to demonetize the precious metal from circulating coinage. This transitional status makes the 1964-D the most heavily produced silver dime in history, with Denver striking over 1.35 billion pieces in anticipation of the composition change. Cataloged by Cuds on Coins on November 27, 2016, this variety occupies a unique position at the intersection of spiked head collecting and RPM attribution, on the most historically significant date in the Roosevelt Dime series.
