Inverted Jenny

Inverted Jenny

The Inverted Jenny (also known as an Upside Down Jenny, Jenny Invert) is a 24 cent 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 is printed 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 philately. A single Inverted Jenny was sold at a Robert A. Siegel auction in November 2007 for $977,500. 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 had lost the auction the previous month. A block of four Inverted Jennys was sold at a Robert A. Siegel auction in October 2005 for $2.7 million. In the wake of the 2008 financial meltdown, prices fetched by Inverted Jennys receded. Between January and September 2014, five examples offered at auction sold for sums ranging from $126,000 through $575,100. Prices eventually recovered, for on May 31, 2016, a particularly well-centered Jenny invert, graded XF-superb 95 by Professional Stamp Experts, was sold at a Siegel Auction for a hammer price of $1,175,000 The addition of a 15% buyer's premium raised the total record high price paid for this copy to $1,351,250. On 15 November 2018, the recently discovered position number 49 stamp was auctioned by Robert A. Siegel Auction Galleries for a new record hammer price of $1,350,000, with an 18 percent buyer's premium raising the total cost to US$1,593,000.
