EXTREMELY FINE. A RARE SOUND AND BEAUTIFULLY CENTERED ORIGINAL-GUM EXAMPLE OF THE 1868 3-CENT Z GRILL.
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, especially in sound, original-gum condition. Our review of past auctions, including Power Search, found precious few sound copies with Very Fine centering. The editors of Stamp Market Quarterly have had no basis to value a stamp graded better than 85 -- the highest grade awarded to date is to the stamp offered here, and only two others share this grade.
With 2009 P.S.E. certificate (OGh, VF 80, SMQ $29,000.00). This is the highest grade awarded to date and only two others share this grade. (Image)
FINE. A RARE PAIR OF THE 1868 3-CENT Z GRILL. ONE OF THE MULTIPLES USED BY JERRY WAGSHAL TO DEMONSTRATE THE TWO SIZES OF Z GRILLS.
Scott Catalogue notes that the Z Grill is identified as having 13-14 points across by 18 points high. This rare pair demonstrates the two different grill sizes.
With 1986 P.F. certificate. Unpriced in Scott as a pair. Scott Retail as singles with no premium for the grill variation. (Image)
