2005 (S) Proof Oregon Silver State Quarter - Doubled Die Reverse WDDR-007

Description

This proof Oregon State Quarter struck at San Francisco carries the doubled die reverse designation WDDR-007 and is attributed under multiple reference systems as Crawford CDDR-007, CONECA 5-R-VIII, and Wexler 2005-S 25¢ Pr OR WDDR-007. The CONECA class 5 designation identifies this as a hub doubling variety with a specific pivot or offset pattern distinct from the class 2 doubling found on the WDDR-003 from the same die series. Oregon's beloved Crater Lake reverse design, depicting the volcanic caldera surrounded by conifer-clad cliffs, features numerous fine design elements that are susceptible to showing doubling artifacts. As a proof issue, this coin was intentionally struck with polished dies on specially prepared planchets at the San Francisco Mint, producing the sharp contrasts between frosted devices and mirrored fields that characterize modern proof coinage.
