Issued in 1911 by the Chinese Imperial Post Office in Tibet, this rare stamp features a multicolor Coiling Dragon design with a black overprint denoting a value of 1 Indian anna. The underlying base is from the 1909–11 Chinese Coiling Dragon issue (Scott IM 50), printed using gravure with variable line perforations. The overprint was applied for localized use in Tibet, where Indian currency circulated alongside Chinese, reflecting the region's complex postal and political status during the late Qing and early Republican periods. The fierce dragon symbolized imperial authority, while the localized surcharge accommodated cross-border mail conventions. Catalogued as Scott TB 3, Michel CN-IM-TB 3, Yvert TB 3, Stanley Gibbons CN-TB C3, and China Stamp Society CN-IM TB3. This mint never hinged example is well centered with full original gum, deep color, and crisp overprint, representing a scarce and significant piece from early Sino-Tibetan philately. Estimate "$360 – 440"
