The Inverted Jenny
You know a stamp is rare when only a hundred of them have been issued. Issued way back in 1918, this stamp had a face value of 24 cents . However, it's the printing error that made this stamp so valuable and unique. The plane depicted on the stamp is the JN-4HM, built by the Curtiss company in the middle of World War I.

Even though almost all the faulty stamps were destroyed, only a few of these rare philatelic items managed to survive. One of them was sold for a whopping $1.35 million at the Robert A. Siegel auction on May 31st, 2016.
A Nod to Benjamin Franklin
1847 has to be the year of stamps in US history. It was also the year when the United States government started selling stamps for purchase for the very first time.

As a nod to the deputy postmaster and one of the Founding Fathers of the USA - Benjamin Franklin - some stamps with his pictures on them were issued in 1847. A block of 16 pieces of these stamps with a fascinating history was allegedly sold at $220,000 .
