What is the worlds rarest stamp?
There are a few stamps of which only one exist, the last unique record breaker was the Swedish 1855 3 skilling stamp printed in yellow instead of green which sold for $2,300,000 (1.5 million+) in 1996. However this stamp pales compared with the great granddaddy of all rarities, the British Guiana 1 cent stamp of 1856 (the so-called “one cent black on magenta”) which has been hailed as the ‘worlds rarest’ for over 120 years, it hasn’t changed hands for 20 years. When it does, the current record will be shattered!
