Find the right stamp sheet at the Post Office? It could get you $15k

One day in 1918, stamp collector William T. Robey walked into his local post office and had his life changed forever. On that day, Mr. Robey discovered a glaring misprint of the Curtiss JN-4 biplane on his sheet of stamps. The plane was upside down. Realizing its significance, he promptly sold the sheet for $15,000 and put money down on a new house. Since then, the stamp, called the Inverted Jenny by collectors, has been fetching $977,500 at a current auction.

History of the Inverted Jenny

The Inverted Jenny (also known as an Upside Down Jenny or Jenny Invert) is a United States postage stamp first issued on May 10, 1918 in which the image of the Curtiss JN-4 airplane in the center of the design appears upside-down; it is probably the most famous error in American philately. Only one pane of 100 of the invert stamps was ever found, making this error one of the most prized in all philately. A center-line block catalogs for $600,000, which is probably low; a single inverted Jenny was sold at a Robert A. Siegel auction in November 2007 for US $977,500.[1] In December 2007 a mint never hinged example was sold for $825,000. The broker of the sale said the buyer was a Wall Street executive who lost the auction the previous month.[2] A block of four inverted Jennys was sold at a Robert A. Siegel auction in October 2005 for US $2.7 million. Read more at Wikipedia ».

For last month's opening of the William H. Gross stamp gallery at the Smithsonian's National Postal Museum in Washington, the Postal Service has reissued the Inverted Jenny, with a face value of $2, in mini-sheets of six with a decorative border. This time, however, they've also printed a rare set of stamps with the plane right-side up. If you've found one of these sheets, IdealNY would like to change your life like William T. Robey. The post office has created 100 sheets of right-side up Jennys and famed collector and philanthropist Sam Malamud is offering $15,000 per sheet to all the lucky finders.
