10c Orange Yellow, Coil (497). Mint N.H. joint line pair, mathematically perfect centering, vivid color on post-office fresh paper

EXTREMELY FINE GEM. A SPECTACULAR MINT NEVER-HINGED JOINT LINE PAIR OF THE 10-CENT 1922 ROTARY COIL, GRADED GEM 100 BY BOTH P.S.E. AND THE PHILATELIC FOUNDATION. THIS IS THE ONLY EXAMPLE TO ACHIEVE THIS PERFECT GRADE.

The 1922 10c horizontal coil, Scott 497, was the last issue of the long and fascinating Washington-Franklin period. It was issued less than a year before the new 1922 series began to appear, though with ample supplies on hand it was not replaced by the 10c Monroe coil until nearly three years later. While it is not a rare coil, Mint N.H. joint line pairs in the highest grades are very elusive. The P.S.E. Population Report records only two joint line pairs graded above 95 -- one at 98 and this example at 100.

Ex Depew. With 2019 P.F. certificate (Gem 100). With 2010 P.S.E. certificate (Gem 100; SMQ $2,100.00).
