Last June 17th, the British Guiana 1¢ Magenta was put on auction at Sotheby’s in New York. This stamp is considered by many to be the world’s rarest. Well, if we look at the British Guiana in terms of monetary value, this stamp is now definitely the most valuable, since its selling price has just set a new world record.
The record-shattering amount of US$9.48 million was the winning bid. The stamp was sold over the phone to a bidder who chooses to remain anonymous.
