This is the first grill to be issued after the experimental A and C grills. It was produced In January 1868, with the 1¢, 10¢ and 15¢ not being printed until almost at the end of the Z grill life span. They were printed for perhaps only a few weeks and as such they are rare. The grill points are facing down and the grill is horizontal (see types of grills).
Only two copies are known to survive. One is in private hands, the other is on display at the National Postal Museum.
The Z grill was discovered in 1913 by William L. Stevenson who created the grill letter classification system. At the time he could not match this grill with any other grills, one year later, because of its unknown nature he assigned the letter Z to this grill.
