Part of the overprinted series marking the advent of the Republic of China, this 2 cent green stamp is originally from the 1897 Coiling Dragon issue. Issued on March 24, 1912, it bears a red vertical overprint in the flowing Sung style (中華民國), printed by the Custom Statistical Department, Shanghai. The base stamp features a detailed dragon design engraved with high precision. With no watermark and varying perforation, it reflects the shifting standards of early Republican philately. The postmark is partial but legible, enhancing its postal history value. Catalogued as Michel CN-IM 96I, Scott CN-IM 148, Yvert CN-IM 85, SG CN-IM 194, CSS CN-IM 186. Estimate "$55 – 85"
