2005-S Doubled Die Obverse WDDO-001

Description

Cataloged by the Wexler Team as 2005-S 25-cent Proof Oregon WDDO-001 and holding the primary DDO position for this proof state quarter, this San Francisco Mint variety features John Flanagan's Washington portrait with hub doubling visible on the obverse design elements. The 2005-S proof Oregon State Quarter was part of the 50 States Commemorative Coin Program, and the Oregon reverse design by Donna Weaver depicts Crater Lake — the deepest lake in the United States, formed in the caldera of the ancient Mount Mazama volcano. As a proof strike, this coin was produced with specially prepared dies on polished planchets, creating the mirror-like fields and frosted devices that characterize modern San Francisco proof coinage. No cross-references to other attribution systems have been established, making the Wexler listing the sole catalog entry. The doubled die obverse mechanism involves hub misalignment during the die-sinking process, where the working hub shifted position between successive impressions into the die steel, creating overlapping design contours visible under magnification. The 2005-S proof Washington Quarter was struck in copper-nickel clad composition at 5.67 grams on 24.3mm planchets. Proof state quarters from the 2005 San Francisco production carry a total mintage of approximately 3.3 million pieces across clad and silver proof sets, making proof die varieties scarcer in absolute terms than their circulation strike counterparts.
