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.
