2005-D Doubled Die Reverse WDDR-006

Description

Another Class VIII tilted hub variety for the 2005-D Oregon State Quarter, this Denver issue carries the attribution Wexler Variety ID: 2005-D 25¢ OR WDDR-006 and the cross-reference CONECA 6-R-VIII. The CONECA classification places this as the sixth reverse variety of this doubling class for the date, confirming systematic research across multiple working dies. Oregon's Crater Lake reverse, designed by Donna Weaver, features the volcanic caldera lake framed by steep rim walls and evergreen trees — geological detail serving as a sensitive canvas for detecting hub displacement. Tilted hub doubling produces a gradient strongest where angular divergence between hub and die is greatest, diminishing toward the tilt axis. The distinction between WDDR-006 and other Oregon DDRs lies in the specific location and magnitude of spread, differing with each die's unique hubbing event. Denver produced Oregon quarters for both circulation and uncirculated coin sets during 2005. The 50 State Quarters Program's popularity ensured thorough scrutiny of every design, and Oregon's compelling reverse drew particular collector attention throughout the variety research community.
