3c Rose, Z. Grill (85C). Huge margins with almost mathematically perfect centering, long and full perforations all around and clearly-defined grill, rich color, cancelled by "Peoria Ill. May 4" circular datestamp and bold letter "B" (postmaster was George C. Bestor)

EXTREMELY FINE GEM. A SUPERB USED EXAMPLE OF THE 1868 3-CENT Z GRILL IN THE FINEST CONDITION ATTAINABLE -- MADE MORE DESIRABLE BY THE STRIKING "B" CANCEL. P.S.E. HAS AWARDED THIS STAMP THE GRADE OF SUPERB 98, WHICH IS THE HIGHEST GRADE AND ONLY EXAMPLE TO DATE.

The 3c Z Grill was in production for only a short period of time before the device was replaced with the F Grill. Only a small number of 3c sheets were fed thru the Z Grill, which accounts for the rarity of surviving examples. Our review of past auctions, including Power Search, found precious few sound copies with Extremely Fine centering, and none that rival this stamp.

P.S.E. encapsulated (Superb 98; SMQ $44,000.00)
