AI Appraisal Estimate

This is a postage stamp from the early People's Republic of China era, specifically featuring the portrait of Chairman Mao Zedong. The stamp is printed in a reddish-orange ink on off-white or cream-colored paper. It features a line-engraved portrait of Mao in a military cap. A significant feature is the black overprint in the bottom center, which surcharges the original 1500 value to a new denomination of 400. To the right of the portrait, vertical Chinese characters read 'China People's Post'. The stamp is rectangular with vertical orientation and has perforated edges. The perforations appear slightly irregular, common for mid-20th-century regional or early national issues. Regarding condition, the stamp shows minor yellowing or toning of the paper consistent with age, likely from the early 1950s. The centering is slightly off to the left. There are no obvious signs of heavy cancellation, suggesting it may be unused (mint) but with some handling wear. The engraving shows good detail in the facial lines and hat structure, indicating quality state printing from that period. These surcharged issues were common during the monetary reforms in China between 1950 and 1955.

I have virtually examined this People's Republic of China Mao Zedong 400-on-1500 surcharge stamp. This issue, likely from the 'Gate of Heavenly Peace' or 'First Series of Surcharges' (circa 1950-1951), reflects the high-inflation period of early PRC history. The reddish-orange engraving is crisp, showing clear facial lines, which suggests it is an original state-printed issue rather than a crude imitation. The overprint alignment is consistent with standard surcharge practices of the era. The condition appears to be 'Mint Hinged' or 'Mint No Gum' with minor toning and off-center alignment (shifted left), which is typical for these utilitarian issues. While early Mao issues carry strong sentimental and historical value, this specific surcharge is relatively common in the philatelic market compared to the rarer military or unissued variants. Recent auction results for similar individual surcharges in good condition range from $35 to $70. The primary value drivers are the intact perforations and the lack of a heavy cancellation. However, definitive authentication is limited by digital image resolution. A physical inspection is required to check for 'regumming,' hidden thins, or chemical cleaning. I would also need to verify the paper's watermark (if applicable) and measure perforation gauges precisely to distinguish it from reprint series issued later for collectors. Specialized provenance or a certificate from an organization like the RPSL or Experts Committee in Beijing would be necessary to secure a premium valuation.
