EXTREMELY FINE GEM. THE 10-CENT I GRILL IS ONE OF THE RAREST OF ALL UNITED STATES STAMPS. ONLY TWELVE USED AND THREE UNUSED EXAMPLES HAVE BEEN IDENTIFIED. THIS IS ONE OF THE FINEST KNOWN.
Starting with the 2013 Scott U.S. Specialized Catalogue, the I Grills have been elevated to major catalogue number status. Collectors will now have to acquire these I Grills in their quest for completeness. We anticipate that collector demand will be difficult to satisfy based on populations we have seen.
Ronald Burns, the foremost authority on the Bank Note grills, records ten used examples of the 10c I Grill, plus an additional two used on the same cover. Three unused examples are also known.
Ex Engel, "Connoisseur", Renne and Floyd. With 1962 P.F. certificate (not specifying the grill type) and 2002 P.F. certificate as an I Grill
