AI Appraisal Estimate

This is a vintage postage or revenue stamp from the Republic of China, issued circa 1948 during a period of significant currency inflation. The stamp features a portrait of Dr. Sun Yat-sen, the founding father of the Republic, centered within an ornate oval frame. The design is printed in a monochromatic purple or violet ink on off-white paper with standard serrated perforations. The upper portion of the stamp displays the sun symbol of the Kuomintang, flanked by Chinese characters indicating the denomination. The lower corners clearly show the numeric '7000' value, reflecting the high-denomination issues typical of the post-WWII Chinese Civil War era. The text across the bottom identifies the postal administration. Regarding condition, the stamp appears to be in used or 'off-paper' state; the perforations show some slight irregular wear and minor foxing/toning consistent with age. There is no visible cancellation mark on the face, but the paper edges exhibit typical softening from handling. The high-quality intaglio printing style showcases fine line work and cross-hatching typical of mid-20th-century philatelic production.

I have conducted a visual examination of the Republic of China (ROC) 1948 Sun Yat-sen Revenue Stamp, featuring the 7,000 Yuan denomination. The stamp exhibits the characteristic monochromatic purple ink and intaglio printing consistent with the high-denomination surcharge issues of the Chinese Civil War era. The condition appears to be 'Fine' for the period; however, I note slight irregular wear on the perforations and visible foxing/toning on the paper stock, which is typical for philatelic material stored in humid Asian climates. The high face value of 7,000 Yuan is a direct artifact of the hyperinflationary period under the Nationalist government, making it a fascinating historical specimen. Market demand for mid-20th-century Chinese revenue stamps is steady but specialized. While many collectors focus on postal issues, revenue stamps (used for taxes or legal documents) attract a different niche. Because these were produced in massive quantities during the currency collapse, this specific denomination is not considered rare. Comparables for uncancelled, off-paper examples generally fluctuate in the modest $5 to $15 range depending on the freshness of the gum (if present) and the absence of hidden defects like thinning. This appraisal is based solely on digital imagery. For a definitive authentication, I would require an in-person physical inspection to verify the watermark (if any), paper fluorescence under UV light, and to check for 're-gumming' or repairs. A high-resolution scan of the reverse would also be necessary to identify hinge marks or thinning. Scientific grain analysis would be required to confirm this is not a modern facsimile. For insurance or high-value sale, I recommend certification by the American Philatelic Expertizing Service (APEX).
