• British Guiana One Cent Black on Magenta, 1856 rare stamp

    British Guiana One Cent Black on Magenta, 1856


    For a very long time, the 1856 one cent "Black on Magenta" of British Guiana was considered to be the world's rarest and most expensive stamp. In 1856, the former colony of British Guiana urgently required an extra supply of stamps and couldn’t wait for a fresh stock of new stamps to arrive from England where they were normally produced. The postmaster of British Guiana asked the publishers of the Official Gazette newspaper in Georgetown to print an emergency issue for local use. Rather crude looking designs were printed in one cent and four cent denominations. One cent stamps were meant for newspapers, while their four cent counterparts were intended for postal correspondence.

    The local designs were printed in black ink on low-quality magenta-colored paper. They featured an image of a sailing ship, the lettering “Black Guiana” and an inscription of the colony's Latin motto "Damus Petimus que Vicissim" ("We Give and We Seek in Return"). The stamp had a rectangular shape with its corners snipped off, which made it look more like an octagon. Each sample was initialed by a post office employee as a security measure against possible forgeries. However, production of the stamps was soon discontinued. In 1873, a 12-year-old Guaianian boy discovered an octagon-shaped one cent "Black on Magenta", postmarked April 4, 1856 and bearing the initials "E.D.W" in his family's attic. He later sold the stamp to N. R. McKinnon, a local collector, for a very small sum. Over the years, the uniqueness of this stamp created an uproar in the philatelic circles, as no other copy was ever discovered. In 1980, it was auctioned to John Dupont at a huge price of $935,000. At present, this rare stamp value is estimated over 9 million dollars.

    Sweden Three Skilling Banco, Yellow Color Error, 1855


    Sweden Three Skilling Banco, Yellow Color Error, 1855 $2.3 million In 1855, Sweden issued its first series of stamps featuring the Swedish coat of arms. The stamps were available in a number of denominations ranging from 3 to 24 Swedish skillings. Each denomination was associated with a different color, which sometimes created confusion in the printing houses. Due to a printing error, one of the three skilling stamps appeared on yellowish orange paper meant for the eight skilling stamp of the same set instead of the usual blue-green color used for this denomination. One copy of the yellow error variety was discovered in 1885 by a young Swedish boy in his grandfather's collection. The exact number of mistakenly printed stamps remains unknown. It is considered to be a one-of-a-kind rarity, as no other copies have been discovered to date. In 1996, the stamp was auctioned to an anonymous collector for $2.3 million.

  • Post Office Mauritius, 1847 rare stamp

    Post Office Mauritius, 1847


    In 1847, the Governor of the Mauritius Island, a British colony located in the Indian Ocean, ordered to issue the colony's first postal stamps. A local watchmaker from the capital city of Port Louis was awarded a contract to produce two nominations: one penny and two pence. During the printing process, the watchmaker erroneously engraved the words "Post Office" instead of the correct words "Post Paid" on the stamps. By the time the error was discovered, over 200 copies of the Mauritius stamps had already been printed and sold.

    According to philatelic experts, less than 30 individual copies of Post Office Mauritius have survived until today. They are valued at $600,000 or more depending on the condition of the particular stamp being sold. In 1993, a cover bearing two of these stamps was auctioned for a whopping $3.8 million, the highest price ever paid for any philatelic item.

  • Hawaiian Missionaries, 1851 rare stamp

    Hawaiian Missionaries, 1851


    The first Hawaiian stamps appeared in 1851. These designs are now referred to as the "Hawaiian Missionaries" because they were frequently used by American missionaries on the islands to send letters back to the continental United States. The new stamps were released in Honolulu in three denominations (2 cent, 5 cent, and 13 cent). Because the first "Hawaiian Missionaries" were crudely engraved and printed on thin and poor quality paper, very few of these stamps have survived and are considered to be extreme rarities.

    The lowest denomination, the 1851 two cent version, is the rarest of the set, with only about 16 copies known to exist today. An unused two cent Missionary is valued at about $760,000, while the same stamp in a used condition can be sold for $225,000.
