1958 Doubled Die Reverse DDR-001

Description

Holding the primary DDR designation for 1958 Proof Roosevelt Dimes, DDR-001 features medium extra thickness on ONE DIME, UNUM, and OF AMERICA with splits visible in both olive and torch stems, accompanied by light extra thickness on UNITED STATES. The stem splits — where the secondary impression separates the single stem line into two parallel traces — rank among the most diagnostically unmistakable doubled die features on Roosevelt Dime reverses. The obverse is classified as ODV-006. Die stage documentation under catalog codes UVC-307 and DMR-006 reveals an unusual progression where the obverse and reverse aged at different rates. Stage A at early die state remains unconfirmed. Stage B records the reverse in mid-die state while the obverse remains in early die state, indicating the reverse deteriorated faster — possibly due to the doubled die's compromised surface integrity. Stage C advances to late die state, marked by a strong die scratch on the rim above the first A of AMERICA, with the obverse reaching mid-die state. This asymmetric die state progression is relatively uncommon and provides collectors with distinct stage-specific markers. Cataloged by VarietyVista, this 90% silver proof dime rewards examination of the stems for splits and the inscriptions for the medium extra thickness diagnostic.
