12c Dull Violet grill (140), an exceptionally choice used example of this very scarce Bank Note grill, this stamp exhibits many strong pronounced grill points, very good color for this stamp, well-centered for this notoriously poorly centered stamp, neat unobtrusive segmented cork cancel, very fine and exceptionally choice, with 1994 P.S.E. and P.F. certificates, Scott retail $2,000.00 photo est.
