1967 Doubled Die Reverse DDR-006

Description

DDR-006 on the 1967 Washington clad quarter presents medium spread on UNITED STATES OF AMERICA and E PLURIBUS UNUM across the reverse, with the reverse die identified as RDV-004. The 1967 quarter is part of the Special Mint Set (SMS) era — from 1965 through 1967, the U.S. Mint produced neither proof sets nor standard uncirculated mint sets, instead offering SMS coins struck on polished planchets with somewhat sharper detail than regular business strikes. No mintmarks appear on 1965-1967 coinage regardless of the production facility. Reported by Timothy Wissert, this variety's obverse die is cross-listed as DDO-006, creating a die marriage where both sides carry documented hub doubling. The RDV-004 reverse die variety designation connects this doubled die to a specific reverse hub type used during 1967 production. Medium spread on both the upper legend and the motto provides two independent diagnostic zones. The SMS production context gives these quarters a distinctive finish between business strike and proof quality, and the polished surfaces can actually aid detection of the medium doubling under proper magnification and lighting conditions.
