The British Guiana One-Cent stamp on display at Sotheby’s

(AP) – 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 Tuesday at 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.

The stamp was expected to bring between $10 million and $20 million. Sotheby’s
said the buyer wished to remain anonymous. The price included the buyer’s
premium.

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