2005-D Doubled Die Reverse WDDR-004

Description

A satin finish specimen from the 2005 Uncirculated Coin Set, this Denver Oregon State Quarter reverse is attributed as Wexler Variety ID: 2005-D 25¢ SF OR WDDR-004 and cross-referenced as CONECA 4-R-VIII, exhibiting Class VIII tilted hub doubling. The SF designation in the Wexler catalog identifies satin finish origin. Oregon's reverse depicts Crater Lake — the deepest lake in the United States, formed in the caldera of Mount Mazama — surrounded by towering cliffs and conifers. This scenic composition provides numerous reference points where tilted hub doubling can manifest. Class VIII doubling occurs when the hub contacts the die at a slight angle, producing displacement varying across the design surface. The 50 State Quarters Program (1999-2008) generated extraordinary public interest in coin collecting, and variety researchers documented errors across all fifty designs with unprecedented thoroughness. The CONECA cross-reference confirms independent verification of the Class VIII classification. Satin finish specimens offer a distinct surface that can enhance subtle hub doubling visibility.
