British Guiana 1c Magenta — World's Rarest Stamp
The British Guiana 1c Magenta is the world's most famous and most valuable single stamp, and only one example is known to exist. Printed locally in 1856 as a crude emergency issue, this lone survivor last changed hands for roughly US$9.48 million in 2014.

What makes it unique
Unlike rare stamps that survive in small numbers, the British Guiana 1c Magenta is genuinely one of a kind: a single confirmed example exists. That uniqueness, combined with a colorful history, is why collectors and the public alike call it the world's rarest stamp.
It was never meant to be a treasure. In 1856 a shipment of regular stamps failed to arrive in the colony, so the postmaster in Georgetown authorized a local newspaper printer to produce an emergency issue. The result is crude by design — typeset rather than engraved, printed in magenta on poor paper, and showing a small sailing ship beneath the colony's Latin motto, Damus Petimus Que Vicissim (roughly, we give and we seek in return).
As a security measure, postal clerks initialed each stamp by hand; this example bears the initials of clerk E.D. Wight. The stamp was also cut octagonally rather than left as a rectangle, giving it the distinctive clipped-corner shape it still has today.
History and record sales
The surviving example was reportedly found by a young Scottish-descended collector in British Guiana in 1873, who sold it for a few shillings. From there it passed through a series of legendary collections, repeatedly setting price records for a single stamp as it changed hands over more than a century.
Its most famous modern sale came at Sotheby's in New York in 2014, where it realized about US$9.48 million including the buyer's premium — a world auction record for a single stamp. The stamp was later acquired by the dealer and auction house Stanley Gibbons. Because only one exists, its market value is not a catalog figure but simply whatever a determined collector is willing to pay on the day it next appears.
