|| 8c Olive Green (560). Mint N.H., mathematically perfect centering, beautiful color and crisp impression, long and full perforations all around
EXTREMELY FINE GEM. AN ABSOLUTELY STUNNING MINT NEVER-HINGED EXAMPLE OF THE 8-CENT 1923 ISSUE, WHICH HAS BEEN GRADED GEM 100 BY P.S.E. -- THIS IS THE HIGHEST GRADE AWARDED TO DATE AND THE ONLY EXAMPLE TO ACHIEVE THIS GRADE.
With 2011 P.S.E. certificate (Gem 100; unpriced in SMQ above the grade of 98, SMQ $1,550.00 as 98). This is the highest grade awarded to date in any category and it is the only example to achieve this grade. This has always been considered the most difficult "key value" of the set to find in well-centered condition. This is supported by the low population report numbers for this stamp in the higher grades. (Image Magnifier)
