AI Appraisal Estimate

This item is an airmail postage stamp from the Republic of China, featuring a biplane flying over a mountainous landscape with a section of the Great Wall of China. The primary color of the stamp is a deep teal or greenish-blue, printed on what appears to be off-white paper. The stamp has perforations along all four edges, indicating it was intended to be torn from a sheet. In the lower left corner, the denomination '15' is prominently displayed in a bold, sans-serif font. The lower right portion features Chinese characters, which, based on the context of 'airmail stamp' and 'Chinese stamp', likely denote the denomination in Chinese currency and 'airmail' or 'air service'. Other smaller Chinese characters are visible across the lower center of the stamp. The scene depicts a single-engine biplane flying horizontally across the top middle, above rolling hills and a distinct stretch of the Great Wall with a watchtower on a formidable peak to the right. The artwork is rendered in a somewhat illustrative style, typical for stamps of this era, suggesting a period before highly intricate photographic reproductions became common. The condition appears to be used, as evidenced by what looks like a cancellation mark or postmark obscuring some of the central details of the landscape and text. This mark consists of an array of small, dark, irregular, and slightly raised shapes, possibly indicating a date or location, though it is not clearly decipherable from this image. The perforations are mostly intact, with no obvious major tears or missing sections. This type of stamp would likely date from the mid-20th century, possibly from the 1920s to the 1940s, a period when airmail services were gaining prominence in China.

Based on my visual examination of this Republic of China Airmail Stamp, 15 Sen (Yuan) with Plane over Great Wall, I can offer the following appraisal. The stamp appears to be a genuine issue from the period, likely mid-20th century, given the design and 'airmail' context. Its condition is used, with a cancellation mark visible, which affects its aesthetic appeal and value compared to an uncancelled specimen. The perforations seem mostly intact, which is a positive, but the clarity of the cancellation is poor, preventing me from identifying specific dates or locations that might add unique provenance. The teal color is consistent with known issues of this period. Market conditions for used Republic of China airmail stamps vary widely based on rarity, condition, and specific issue. While this particular design is iconic and generally popular among collectors of Chinese philately, the visible cancellation and potential fading (difficult to assess definitively from an image) limit its top-tier value. Comparables of this stamp in fine used condition typically fetch in the $25-$50 range. Higher values would be expected for unused examples or those with particularly clear and desirable cancellations. Demand for ROC airmail stamps remains consistent, driven by collectors specializing in early aviation and Chinese postal history. This specific issue is not considered exceptionally rare in used condition. The primary factor impacting its value is its used state and the somewhat heavy, indistinct cancellation. It is crucial to note that this authenticity verification is based purely on visual inspection of the provided image. For full authentication, an in-person examination is essential to inspect the paper type, watermarks (if any), printing method (e.g., lithography vs. typography), and gum condition (if unused). Microscopic analysis could confirm printing details and rule out counterfeits. Provenance documentation, such as where and when it was acquired, would also enhance its verifiable history. Without these, my assessment of authenticity is limited to what can be gleamed from a digital photograph.
