Description
RPM-003 records a second S/S Southeast repunched mintmark variety on the 1970-S Proof Washington Quarter, distinct from RPM-002 despite sharing the same directional displacement — this variety originates from a different die pair. Catalogued UVC-1211 and DMR-006, three die stages are documented: Stage A (early die state), Stage B (mid die state), and Stage C (late die state). The 1970-S Washington Quarter was produced only as a clad proof at the San Francisco Mint — no business-strike counterpart exists for this date — struck in copper-nickel clad composition under John Flanagan's design and specially finished for collector sets. The existence of two independent S/S Southeast RPM varieties for this date reflects the reality that multiple dies were prepared for proof production and that mintmark repunching could recur on different dies in the same direction.
