(594). Well-centered for this difficult issue, unusually wide margins,
dark shade and sharp impression, light cancel, two small corner creases and
tiny thin spotVERY FINE APPEARANCE. ONE OF THE MOST ATTRACTIVE EXAMPLES OF SCOTT 594.
The 1c Green, Scott 594, is waste from a horizontal rotary printing used to make coils. At the beginning or end of a coil-stamp print run from the 170-subject rotary plates, some leading or trailing paper was produced that was too short for rolling into 500-stamp rolls. In 1919 the Bureau devised a plan to salvage this waste by perforating and cutting the sheets into panes. They were put through the 11-gauge flat-plate perforator in use at the time, giving the sheets full perforations on all sides. In 1923 coil waste from the new 1c and 2c rotary production was turned into stamps later classified as Scott 578-579 and 594-595. These were the last of the coil-waste issues. The existence of Scott 594 was not reported until four months after the final sheets were delivered, and the 1c Rotary Perf 11 was soon recognized as one of the rarest United States stamps. There are today fewer than 100 confirmed examples of Scott 594.
