1c Ultramarine, Grill (134). I. Grill, original gum, very lightly hinged, brilliant color on post-office fresh paper, clearly-defined I grill which is the smaller of the two grill sizes, beautiful centering with wide and balanced margins

EXTREMELY FINE GEM. A STUNNING ORIGINAL-GUM EXAMPLE OF THE 1870 ONE-CENT NATIONAL BANK NOTE ISSUE WITH THE SCARCER I GRILL. THIS IMPRESSIVE STAMP HAS BEEN AWARDED THE GRADE OF XF-SUPERB 95 BY P.S.E. -- THIS IS THE HIGHEST GRADE AWARDED TO DATE TO EITHER GRILL TYPE.

In 2004 we started to distinguish between the H and I Grills in our catalogue descriptions and research, in an effort to establish relative scarcity. It is our opinion that the Scott Catalogue should list the H and I Grills separately, as they do for the A, B, C, D, Z, E and F Grills of the 1867-68 Issue. According to the Scott Catalogue, the H Grill is found on all values, and the I Grill is found only on the 1c, 2c, 3c, 7c, 10c and 15c. Certified copies of the 6c are also known, and the 24c and 90c are reported to exist as well. We have only offered four other unused 1c I Grill stamps since we started keeping our detailed records.

Ex Anderson. With 1992 P.F. and 2008 P.S.E. certificates (OGph, XF-Superb 95). This is the highest grade awarded to date to either grill type and the only example to achieve this grade. Scott Catalogue and SMQ do not list the I grills separately, even though they deserve separate listings.
