1970-S Repunched Mintmark RPM-001

Description

Cataloged by VarietyVista as UVC-547 with die marriage reference DMR-004, the 1970-S Repunched Mintmark RPM-001 is a proof Roosevelt Dime exhibiting an S/S Tilted repunched mintmark — the primary catalog entry for repunched mintmarks on the 1970-S proof dime. The RPM-001 designation typically indicates the variety was either the first documented or the most visually prominent example discovered for this date and mint combination, establishing it as the reference standard against which other 1970-S proof dime RPMs are compared. The die state documentation lists 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). The tilted repunching produces a rotational displacement between the two S impressions, where the secondary letter appears to pivot around a central point relative to the primary, creating varying degrees of separation at different points around the letter's circumference. John R. Sinnock designed the Roosevelt Dime in 1946 to honor President Franklin D. Roosevelt. The 1970-S proof was struck at the San Francisco Mint in clad composition (91.67% copper, 8.33% nickel outer layers bonded to pure copper) at 2.27 grams with a 17.9 mm diameter and a reeded edge. The proof manufacturing process, with its polished dies and planchets, captures mintmark detail with high fidelity, making proof coins particularly suitable for RPM collecting. As the first-numbered entry among six documented RPMs for the 1970-S proof dime, RPM-001 anchors the variety family for this date and serves as the baseline example of 1970-S proof dime mintmark repunching in the VarietyVista reference system.
