1970-S Repunched Mintmark RPM-014

Description

Cataloged by VarietyVista with preliminary die marker codes (UVC and DMR pending final assignment), the 1970-S Repunched Mintmark RPM-014 is a proof Jefferson Nickel exhibiting an S/S Tilted repunched mintmark — where the San Francisco mintmark punch was applied twice with the second impression at a slightly different rotational angle, creating a tilted or rotated displacement between the two S letter forms rather than a simple directional shift. This tilted orientation produces a distinctive diagnostic signature where different portions of the secondary S show varying degrees of separation from the primary, appearing to diverge at some points while nearly overlapping at others. The die state progression documents Stage A with both obverse and reverse in early die state, Stage B as mid-die-state (unconfirmed), and Stage C as late die state (unconfirmed). As a proof coin struck at the San Francisco Mint, this nickel was produced on polished planchets using polished dies with multiple impressions per strike, yielding the mirror fields and frosted devices characteristic of the proof manufacturing process. Felix Schlag's obverse design portrays Thomas Jefferson in left-facing profile, while the Monticello reverse shows the mansion's distinctive neoclassical portico. Composed of 75% copper and 25% nickel, the coin weighs 5.00 grams with a 21.2 mm diameter. The 1970-S proof nickel was produced exclusively for inclusion in proof sets sold to collectors, with a proof set mintage of approximately 2.63 million for that year. The RPM-014 numbering indicates this is the fourteenth documented repunched mintmark variety for the 1970-S nickel, reflecting the diversity of hand-punch placement variations that accumulated across the San Francisco Mint's die production for this date.
