2c Black, Z. Grill (85B). Well-centered, beautiful sharp grill points clearly showing the horizontal ridges unique to the Z grill, cancelled by neat red New York City "Post Office" datestamp

EXTREMELY FINE. A NOTORIOUSLY DIFFICULT STAMP TO FIND WELL-CENTERED. ESPECIALLY RARE WITH A RED DATESTAMP CANCELLATION.

The plates used to print the Black Jacks did not provide enough space between subjects for the large 12-gauge perf holes. Consequently, most Black Jack stamps have perfs touching the design on one or two sides. This scarcity of four-margined copies multiplies exponentially when the Z Grill is factored into the equation. Only a small quantity of 2c sheets were grilled during the period when the Z device was active -- after the D Grill, the Z is the rarest of Black Jack grilled stamps.

Ex Puliafito. With 1995 P.F. certificate
