History of the British Guiana 1c Magenta
The unique specimen dates back to 1856, when it was issued as an emergency stopgap in Demerara, the capital of what was then the British colony of British Guiana, now known as Georgetown. According to Stanley Gibbons, the provisional stamps were printed on low-quality magenta paper after a routine shipment of postage supplies from London failed to reach South America. Only a single copy of this emergency printing has survived to the present day.
After being rediscovered in 1873 by a Scottish schoolboy who sold it for six shillings, the stamp passed through several private collections, according to ownership records detailed by Stanley Gibbons. In 2021, London-based stamp merchant Stanley Gibbons acquired the specimen for £6.2 million, equivalent to approximately €7.2 million. The company stores the item in a secure vault for protection when it is not on public exhibition.
