Philatelists, start your engines: The U.S. Postal Service plans to issue a collector stamp commemorating “the most famous error in the history of U.S. stamps”: the 1918 misprint that produced an upside-down Curtiss-Jenny biplane.
The reprinted inverted Jenny stamp will be issued Sept. 22 for $2. The original inverted Jenny was issued in 1918 and cost 24 cents. The postal service is using the original engraved dies of the 1918 stamp in the design of the 2013 edition.
If you happen to own one of the originals, good for you. The Postal Service says collectors have accounted for nearly all of the 1oo inverted Jennys that were produced. One recently sold at auction for $625,000.
