2005-S Doubled Die Reverse WDDR-002

Description

Attributed by the Wexler Team and extensively cross-referenced as Kenneth Russell Cross References Crawford CDDR-001, CONECA 1-R-VIII, and Wexler Variety ID 2005-S 25c Pr OR WDDR-002, this doubled die reverse on the 2005-S Oregon State Quarter Proof displays doubling on the left ends of the lower left branches on the second tallest tree, with additional doubling on the land line above the 5 in the date and above the M of UNUM. No significant die markers were detected on either the obverse or reverse, meaning attribution relies entirely on the doubling characteristics themselves — an uncommon situation that demands careful examination of the specific tree branch positions to confirm the correct variety. The Oregon State Quarter reverse features Crater Lake with surrounding forest trees, designed by Donna Weaver, providing the arboreal elements where branch doubling manifests. The triple cross-referencing across Crawford, CONECA, and Wexler catalogs indicates strong collector and researcher awareness of this variety. The CONECA classification 1-R-VIII identifies this as a Class VIII modified hub doubling pattern, where the doubling resulted from a late-stage modification to the hub design rather than simple hub-to-die misalignment. The 2005-S proof was struck at the San Francisco Mint on polished planchets in copper-nickel clad composition (outer 75% Cu / 25% Ni bonded to pure Cu core), weighing 5.67 grams with a 24.3 mm diameter. As a proof State Quarter, this coin was distributed through annual proof sets and Silver Proof Sets. The absence of die markers makes the tree branch doubling and land line displacement the sole attribution features, best examined under 10x magnification against the proof's mirrored fields.
