1923, 2¢ Harding, rotary press printing, the rare perf 11 (Scott 613), well-centered for this very rare and difficult stamp (Scott's value is for a grade of Fine), with a partial black duplex cancel; light corner crease at top right in no way detracts, Fine, only 50 examples recorded to date, this one of the most attractive examples extant, with 1993 P.F. and 2019 P.S.E. certificates.
Scott $35,000. (Image)

Estimate $30,000-40,000
