THIS IS THE FINEST KNOWN EXAMPLE OF THE 1868 90-CENT F GRILL. THIS SUPERB STAMP HAS BEEN AWARDED THE PERFECT GRADE OF GEM 100 BY P.S.E.

The 90c stamps used to make grilled issues were printed on a thick stock of paper. It is likely that sheets remaining from the pre-grill period were used and that the thinner paper introduced in 1868 had not been used for the 90c value. Two characteristics of 90c F Grill stamps are poorly punched perforations and generally poor centering.

A review of the P.S.E. Population Report statistics for the grilled issues reveals how rare this 90c stamp truly is. Only one other 1867-68 grilled stamp in any condition -- used or unused -- has achieved a grade of 100 (15c used). Even the very common 3c F Grill stamps have not had an example grade 100. To achieve this grade with the top value of the issue is remarkable.
