Rare 1856 British Guiana One-Cent Magenta Stamp Sets Record, Selling for $9.5M in NYC

A 1-cent postage stamp from a 19th century British colony in South America has become the world’s most valuable stamp—again. The 1856 British Guiana One-Cent Magenta sold last Tuesday at an auction in New York for $9.5 million, Sotheby’s said. It was the fourth time the stamp has broken the auction record for a single stamp in its long history.

David Redden, Sotheby’s vice chairman, called the sale “a truly great moment for the world of stamp collecting.”
