6. The 1855 Sweden 3 Skilling Banco – $2.3 Million
This one could be a game-changer for anyone lucky enough to own it. The 3 Skilling Banco is Sweden’s rarest stamp, with only one known copy in circulation. It sold for $2.3 million in 2010. The cool part? It’s another printing error, proving mistakes really do pay off.
7. Mauritius “Post Office” Stamp – $1.148 Million
The Mauritius “Post Office” stamps are famous for their rarity and charm. Issued in 1847, these beauties were printed with “Post Office” instead of “Post Paid.” A small mistake, but it made a huge difference in price! A cover with two of these stamps sold for $1.148 million in 1993.

10. The 1868 Benjamin Franklin Z Grill – $3 Million
This unique stamp features a grill-like embossing pattern meant to prevent counterfeiting. Only two of the Benjamin Franklin Z Grill stamps exist, making it one of the most sought-after U.S. stamps.

These stamps feature an image of the U.S. Capitol flipped upside down. Another classic printing error, these stamps were part of the 1869 Pictorial series and have fetched as much as $800,000. A little flip, a lot of cash!
