EXTREMELY FINE GEM. A MAGNIFICENT MINT NEVER-HINGED EXAMPLE OF THE ICONIC 24-CENT 1918 AIR POST ISSUE, WITH THE PERFECT P.S.E. GRADE OF GEM 100.
With 2010 P.S.E. certificate (Gem 100; SMQ $3,250.00). Only three other Scott C3s share this perfect grade, with none higher. Remarkably, despite offering the majority of the existing Scott C3a 24c inverts over the years, this is the first Gem 100 Scott C3 the Siegel firm has offered at auction
