Twenty-seven confirmed examples exist of this most famous stamp of India. This one illustrated is ex-Dawson, and although cut-to-shape, it's large margins and otherwise fault-free appearance place it among the better of the survivors. Stanley Gibbons list it as SG 18a, and price the stamp from £50,000 to £200,000 (or €57,000 to €228,000). The considerable variance in price quoted by Stanley Gibbons reflects the difference between a cut-to-shape example and the finest stamp known.
