EXTREMELY FINE GEM. A SPECTACULAR MINT NEVER-HINGED EXAMPLE OF SCOTT 505, WHICH IS GRADED SUPERB 98 BY P.S.E.
During the production of the normal 2c plate No. 7942, three positions were noted to be defective. The plate was sent back to the siderographer, who burnished out the three positions and mistakenly re-entered them using a transfer roll for the 5c stamp. The error passed unnoticed and the sheets were issued to the public as Perf 10, Imperforate and Perf 11 (Scott 467, 485 and 505).
With 2018 P.S.E. certificate (Superb 98; SMQ $4,250.00). Only two have graded higher (both 100) and only nine others share this desirable grade
