EXTREMELY FINE GEM. A STUNNING USED EXAMPLE OF THE 1868 2-CENT Z GRILL.
As experienced collectors know, Black Jacks with perforations clear of the design are scarce, and those with the Z Grill are rare.
With 1998 and 2004 P.F. certificates noting red and black cancels. The way they are struck makes us think the cancelling device was first used with one color and was re-inked in the second color before this was cancelled, causing the two colors to display.
