FINE. A SCARCE SOUND EXAMPLE OF THE ONE-CENT ROTARY PERF 11 ISSUE, SCOTT 594. ONE OF THE RAREST 20TH CENTURY STAMPS AND ESPECIALLY DESIRABLE WITH THIS CLEAR CIRCULAR DATESTAMP CANCEL.
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. 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.
Our census of Scott 594, available at our website at: http://www.siegelauctions.com/dynamic/census/594/594.pdf , contains 92 used singles, four used pairs and five covers (including one with a pair) for a total of 106 used stamps. Most have perforations either in on one or more sides and/or have faults. Less than half a dozen examples have clear circular datestamps such as the example offered here.
