1970-S Repunched Mintmark RPM-005

Description

Cataloged by VarietyVista as UVC-551 with die marriage reference DMR-008, the 1970-S Repunched Mintmark RPM-005 is a proof Roosevelt Dime displaying an S/S North repunched mintmark — sharing the same general directional classification as RPM-006 but originating from a different working die, as confirmed by the distinct UVC and DMR catalog numbers. 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 existence of two S/S North varieties for the same date (RPM-005 and RPM-006) illustrates how multiple dies can experience similar misalignment patterns independently — each die preparation specialist may have made a comparable northward placement error, but the resulting repunched mintmarks and their accompanying die markers are unique to each individual die. The 1970-S proof Roosevelt Dime was produced at the San Francisco Mint using the proof manufacturing process that yields mirror fields and sharp device definition. John R. Sinnock's design honors President Franklin D. Roosevelt with the obverse portrait and the torch-and-branches reverse motif. Struck in clad composition (91.67% copper, 8.33% nickel outer layers over pure copper) at 2.27 grams with a 17.9 mm diameter and a reeded edge, the proof dime's small diameter makes mintmark examination under magnification essential for distinguishing between the multiple RPM varieties documented for this date. Differentiating RPM-005 from RPM-006 requires careful comparison of the specific die markers associated with each variety's unique UVC code, as the primary mintmark displacement direction alone is insufficient to identify the correct catalog attribution.
