In addition to the 2.2 million sheets printed with the plane inverted, the Postal Service announced it also printed 100 "non-inverted Jenny" souvenir sheets, with the plane flying right side up. All sheets are individually wrapped in sealed envelopes to recreate the excitement of finding an Inverted Jenny when opening the envelope and to avoid the possibility of discovering a corrected Jenny prior to purchase. Individuals purchasing one of the 100 non-inverted Jenny sheets find a congratulatory note inside the wrapping asking them to call a phone number to receive a certificate of acknowledgement signed by Postmaster General Patrick Donahoe. A non-inverted sheet purchased by Gail and David Robinson of Richmond, Virginia, was sold in June 2014 by Siegel Auctions "Rarities of the World" for $51,750, with the 15% buyer's premium.
