1923 1c green, Rotary, perf. 11, unused without gum, well centered for this difficult issue with perfs clear (often found with perfs in), small paper flaw and a tiny natural inclusion at bottom, fine, with 1961 and 2019 Philatelic Foundation Certificates. One of the rarest 20th Century United States stamps in unused condition (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. Siegel Census of unused examples of Scott 594 records only 18 (!) copies. Of these only 11 have any gum, and three of those have perforated initials of Crowell Publishing Co. of Springfield, Ohio, which some collectors regard as equivalent to a cancel. The example offered here is Census No. 594-OG-05 (Scott Catalogue notes "both unused and used are valued with perforations just touching frameline on one side") (catalogued as unused without gum) cat. $35000 (Cat No. 594) (Image)

1923 1c green, Rotary, perf. 11, light machine cancel, fresh color, trivial short perforation at bottom right, otherwise fine, ex-Grunin, with 1963 and 2019 Philatelic Foundation Certificates. Of the 15 known examples (all used), only five have machine cancels (the other ten have "Kansas City, MO" precancels) and only two are completely sound (the other two have varying degrees of faults, far more significant than the "short perf" mentioned here). This stamp is listed in the Siegel Census as 596-CAN-03. A major 20th Century U.S. Rarity, valued in Scott catalogue in the grade of fine, cat. $200000 (Cat No. 596) (Image)

1923 2c black, Rotary perf. 11, machine cancel, fine, completely sound, with 1958 and 2019 Philatelic Foundation Certificates. Warren G. Harding, the 29th President, died in San Francisco on August 2, 1923 and a Harding memorial stamp, printed in black was rushed into production. The first flat plate printing (Scott 610) was issued on September 1, 1923 in his home town of Marion, Ohio, followed less than two weeks later by the normal perf. 10 rotary press printing (Scott 612) on September 12. The 2c Harding Rotary perf. 11 stamp was discovered in 1938 by Leslie Lewis of the New York firm, Stanley Gibbons Inc. Gary Griffith presents his hypothesis in United States Stamps 1922-26, that rotary-printed sheets of 400 were first reduced to panes of 100 and then fed through the 11-gauge perforating machine normally used for flat plate sheets, cat. $40000 (Cat No. 613) (Image)
