Description
Medium spread on WE TRUST, mintmark, 88 of date, and TY of LIBERTY. Cross-referenced as FS-101. 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.
