Issued in January 1947, this complete sheet of 100 postage due stamps represents the final phase of China’s hyperinflationary postal era. Each stamp bears the denomination of 400 Chinese dollars and was produced at the Dah Tung Book Co. printing house in Shanghai. Designed in a deep purple-brown shade and printed using lithographic techniques, the stamp features prominent Chinese script characters framed in a symmetrical, ornamental design. These were issued without watermark on thin paper and intentionally ungummed, aligning with the utilitarian nature of postage due labels during periods of financial instability. The stamps are line perforated at gauge 14, and the bottom margin of the sheet includes an imprint identifying the printer. Catalogued as Michel CN-IM P89, Scott CN-IM J98, Yvert et Tellier CN-IM T80, Stanley Gibbons CN-IM D921, and China Stamp Society CN-IM PD121, this mint never hinged (MNH) sheet is a pristine and rare survivor from a turbulent moment in China’s postal and economic history, when denominations struggled to keep pace with rising inflation. Estimate "$150 – 250"
