#C3a, 24c Carmine rose and blue, Center Inverted, position 3, natural straight-edge at top, deep rich colors, part o.g., fine. The 1919 Twenty Four Cent Inverted Jenny is one most recognized and desired rarities in all of philately. Its legendary status began the moment the stamp was issued in May 1918, when William T. Robey purchased an entire error sheet of 100 at the New York Avenue Post Office window in Washington D.C. - just one day after the stamp was issued - May 14th. Within one week Robey sold the sheet for $15,000.00 to the well-known Philadelphia stamp dealer Eugene Klein (an impressive return on his initial $24.00 investment). Shortly thereafter Mr. Klein sold the sheet to the renowned, yet eccentric collector, Col. Edward H.R. Green for $20,000.00. Col. Green asked Klein to break up the sheet for him into singles and blocks, and instructed him to sell all but the few key position blocks. What is puzzling is how, given the immediate attention created by a spectacular new error, so many of the stamps from the sheet have been poorly handled and stored over the years. In fact, there are at least seven examples whose whereabouts are unknown and presumably lost to philately. A great many of the known copies have varying degrees of faults and some even have lost all of their original gum. Improper hinging has caused a significant number of the faults, often thinning or creasing the stamps. That is why this copy, despite the natural straight-edge, is a highly desirable example of one of the most important errors in philately.An especially fresh Twenty Four Cent Inverted Jenny.
