1990-D Doubled Die Reverse WDDR-001

Description

Cross-referenced as both Crawford CDDR-001 and Wexler Variety ID: 1990-D 10-cent WDDR-001, this doubled die reverse on a 1990 Denver Mint Roosevelt Dime displays a very close spread towards the center on USA and ONE DIME. The inward-directed spread indicates that the second hub impression was displaced slightly toward the center of the die relative to the first, compressing the design elements rather than spreading them outward. Reverse die markers include a small die gouge to the right of the top of the O in ONE and a die scratch running north from the top of the E in ONE. No obverse markers were noted. The dual cross-reference under both the Crawford and Wexler systems demonstrates that Roosevelt Dime varieties benefit from multiple independent research frameworks — Ted Crawford's CDDR numbering system focuses specifically on Roosevelt Dime doubled dies, providing specialized coverage alongside Wexler's comprehensive cross-denomination catalog. The 1990-D Roosevelt Dime was struck at the Denver Mint during the modern clad era, when dimes were produced from a copper-nickel clad composition bonded over a pure copper core. John R. Sinnock's original Roosevelt design, introduced in 1946, was in its forty-fourth year of continuous production, and the Denver Mint's high-volume output made die varieties statistically likely across the many die pairs consumed during the annual production run.
