2017 (P) Frederick Douglass National Historic Site Quarter - Doubled Die Reverse WDDR-019

Description

WDDR-019, a DDR for the 2017 Frederick Douglass National Historic Site quarter, reflects the productivity of this coin design for variety discoveries. Attributed by the Wexler Team under Wexler Variety ID 2017-P 25c DC WDDR-019, this identifies a distinct working die that received imprecise hubbing at the Philadelphia Mint. The hubbing process requires the design hub to impress the working die under enormous hydraulic pressure, and any movement between successive impressions — rotational, lateral, or angular — transfers a doubled image. That doubled die then reproduces the error on every coin it strikes, potentially numbering in the tens of thousands before retirement. The volume of Frederick Douglass DDR varieties suggests whatever caused the hub misalignment may have been persistent rather than isolated. Thomas Hipschen's reverse composition, blending portraiture, furniture, architecture, and landscape, presents multiple zones where doubling can manifest, and experienced variety hunters systematically examine each zone when searching for new varieties.
