EXTREMELY FINE GEM. THIS STUNNING MINT NEVER-HINGED STAMP HAS BEEN AWARDED THE GRADE OF GEM 100 BY P.S.E. -- THIS IS THE ONLY EXAMPLE TO ACHIEVE THIS GRADE AND ONLY ONE HAS GRADED HIGHER.

With 2009 P.S.E. certificate (Gem 100; unpriced in SMQ above the grade of 98, SMQ $1,000.00 as 98). Only one has graded higher to date (which recently realized $7,500 hammer in our 2009 Rarities sale), and this is the only example to achieve this grade.
