1946-S Doubled Die Obverse DDO-010

Description

VarietyVista assigns this 1946-S Roosevelt Silver Dime the die markers UVC-106 and DMR-014, documenting a multi-variety die pairing where the obverse is classified as ODV-001 and listed as DDO-001, while the reverse carries designations as RPM-003 and MMS-001 (Trumpet tail). DDO-010 itself shows medium spread affecting the date, John R. Sinnock's designer initials JS (reading top to bottom), and the word TRUST — three obverse elements spanning from the lower right to upper right of the design, defining the zone where hub displacement exceeded the medium visibility threshold. Three die stages map this die pair's production life: Stage A (EDS) is unconfirmed, Stage B documents Mid Die State with a die scratch running from the mintmark to the I of PLURIBUS on the obverse, and Stage C shows both obverse and reverse in Late Die State. The Stage B die scratch connecting the mintmark to PLURIBUS is a particularly useful diagnostic, as it provides a single linear feature spanning a significant distance across the obverse that is easy to identify and difficult to confuse with other die markers. The trumpet tail designation on MMS-001 describes a specific misplaced mintmark configuration where a secondary mintmark impression appears to curve outward from the primary mintmark position, resembling the bell of a trumpet — a visually distinctive feature that adds collector appeal beyond the standard DDO classification. As a 1946-S Roosevelt Silver Dime — the inaugural year of the Roosevelt Dime series from the San Francisco Mint — this coin was struck in 90% silver at 2.5 grams. The convergence of DDO, RPM, and MMS varieties on a single die pair makes this an exceptionally information-rich first-year issue.
