The Chinese stamp Scott CN-IM 814, issued in 1948 as part of the Dr. Sun Yat-sen - Surcharges series, is documented in dark green. However, the observed specimen appears in the traditional olive green shade, which is not recorded in any known catalogs. The stamp measures 22 x 26 mm and was printed using typography by Central Trust and Union Press (O). It is a daily issue with variable perforation and a denomination of 15,000 Chinese 10-dollar bills. Unlike many other stamps, this issue is ungummed. Since no official record of an olive-green variant exists, this could be a rare or potentially unique color deviation. Further analysis and expert verification may be necessary to confirm its authenticity and value.
