1988-S Doubled Die Obverse DDO-001
Error
Description
The 1988-S Doubled Die Obverse DDO-001 is a doubled die obverse (DDO) variety, where a misalignment during the die hubbing process created visible doubling on the obverse design elements. This variety was discovered on the 1988 (S) Proof Kennedy Half Dollar, part of the Kennedy Half Dollars Clad and Silver Proof 1971 to Date series. Die markers: UVC-278 DMR-002 Stage A: Obverse and Reverse are EDS Stage B: MDS (unconfirmed) Stage C: LDS (unconfirmed). Cross-referenced as FS-101. Proof. FS-101. First reported proof coin with a hub doubled mintmark. Photographs of modern deep cameo proof coins are very difficult to take. The sandblasting for the frosted image nearly destroys the contrast needed for good photographs, not to mention its effect on the sharpness of the doubling.
