1918 Inverted Jenny Stamp Error Leads to Multimillion-Dollar Collectible
In 1918, a Washington clerk purchased a sheet of 100 airmail stamps featuring the Curtiss JN-4 biplane, only to discover the airplane was printed upside down—a rare printing error known as the Inverted Jenny. This mistake occurred because the stamp required two separate color printings. Only 100 such error stamps were sold, making them highly valuable collectibles. Over a century later, one of these stamps sold for over two million dollars at auction, highlighting its significance in American philatelic history.
