Coil waste
Coil waste is a type of U.S. stamp made from damaged or unusable printing stock intended for use as coil stamps and is a term applied to several stamp issues of the late 1910s and early 20s. Sometimes in the printing of coils on rotary presses, several stamps from the run were deemed unusable for coil production. Instead of discarding these, the Bureau of Engraving and Printing processed them through the flat-plate perforating machine to finish them as fully perforated stamps. These finished products are known as coil waste. While seemingly identical to normal fully perforated issues (which were printed on flat plate presses), coil waste stamps are distinguishable by their size: their designs are slightly wider or longer than normal because rotary press printing slightly stretches an image.
The stamps removed from coil production in the late teens and early twenties were "discarded as unfit," according to a report from a director of the Bureau of Engraving and Printing "on account of narrow margins, too close perforations, and other reasons."
In 1923, during the production of the U. S.
Several extremely rare stamps from this period sometimes misidentified as coil waste were produced from the waste printing of sheet stamps. These include another 1¢ Franklin issue (Scott #596) and the perforated 11 rotary press Harding Memorial stamp (Scott #613).[2]
