1. Inverted Jenny Stamp 

The Inverted Jenny is one of the most famous and valuable stamps in philatelic history. In 1918, the U.S. Postal Service issued a 24-cent airmail stamp featuring a biplane (the Curtiss JN-4) printed upside down by mistake.

2. British Guiana 1c Magenta  

The British Guiana 1c Magenta is the world's rarest and most valuable stamp. Printed in 1856 in British Guiana (now Guyana), it was issued hastily when a shipment of stamps from England failed to arrive.

3. Treskilling Yellow Stamp 

The Treskilling Yellow is one of the most famous errors in Swedish philately. In 1855, the Swedish Postal Service issued a series of stamps with different denominations, including a three-skilling stamp intended to be printed in blue-green.  

While such discoveries are rare, they serve as a reminder of the enduring allure of philately and the potential for remarkable treasures to lurk within the pages of ordinary correspondence.
