Welcome to the home of the world's most expensive stamp, the British Guiana ONE CENT black on magenta. 

On the 8th of June 2021 Stanley Gibbons threw its hat into the ring during an auction at Sotheby's New York and entered a bidding war for this rarest of philatelic treasures. It was an intense bidding process but when the dust settled the Stanley Gibbons management team of Graham Shircore, CEO, and Victoria Lajer, MD, emerged victorious, with the hammer dropping on a final bid of $8.3million. 

On the 16th of July, just over a month after the sale, the stamp arrived in London and our plans for this piece of history could begin. We intend to put the stamp on free public display at different intervals throughout the year so that more people can enjoy this unique piece and discover its fascinating story

We are also working with a company called Showpiece to offer fractionalised ownership of the stamp. This is a world first for a philatelic item and will again allow more people to become a part of this stamp's history. 

“The British Guiana 1c Magenta really is the Holy Grail of philately. It’s truly one of a kind, and we’re delighted to be welcoming it back on to British soil where we hope it will remain,” 

Graham Shircore, CEO of Stanley Gibbons
