2005-S Doubled Die Reverse DDR-004

Description

Featured on the Oregon entry in the 50 State Quarters program, DDR-004 on the 2005-S silver proof displays medium spread in the lower volcano — the lower slopes and base of Crater Lake's volcanic caldera depicted on the reverse. Oregon's design showcases Crater Lake, the deepest lake in the United States, formed within the collapsed remnant of Mount Mazama, with the "lower volcano" referring to terrain beneath the lake surface and surrounding rim. The medium spread on this sculptural element produces visible displacement across the mountain's contours rather than flat lettering. This is a silver proof, struck in 90% silver composition at the San Francisco Mint — a premium collector version distinguished from copper-nickel clad proofs also produced that year. Die markers UVC-1749 and DMR-006 confirm the working die across three documented states: Stage A with reverse and obverse in Early Die State, Stage B in Mid Die State (unconfirmed), and Stage C in Late Die State (unconfirmed). Examine the lower volcanic formation under 5x to 7x magnification, comparing terrain contours against an undoubled specimen to identify the medium spread.
