According to "Jenny" by George Amick (Amos Press, 1986), the original sheet of 100 Inverted "Jenny" stamps was purchased for $24 by William T. Robey at the New York Avenue Branch Post Office window in Washington D.C., on May 14, 1918, one day after the stamp was first placed on sale at the main post office. On May 20, Robey sold his sheet for $15,000 to Eugene Klein, a Philadelphia stamp dealer. Klein had already arranged to sell the sheet to Col. Edward H. R. Green for $20,000. Colonel Green instructed Klein to divide the Inverted "Jenny" sheet into singles and blocks, and to sell all but a few key position blocks. $0 (Image)
