AI Appraisal Estimate

This item is a postage stamp from Ecuador, denominated '5 C.' or 'Cinco Centavos.' The stamp is rectangular in shape and predominantly features a dark green coloration on a white or off-white background, suggesting it is part of a larger sheet given the perforations visible on the left and top edges. The design commemorates the 'Bicentenario de la Mision La Condamine,' marking the years '1736' and '1936.' The central motif consists of three oval portraits of historical figures, likely members of the French Geodesic Mission, set against a background that appears to depict mountainous or natural scenery with what look like stone markers or monuments on either side. Below the central portraits, the text 'BICENTENARIO DE LA MISIÓN 1736 LA CONDAMINE 1936' is prominently displayed. The words 'CORREOS DEL ECUADOR' are arched across the top. The denomination '5 C.' appears in both the upper left and upper right corners, and also in the lower left and lower right, where '5 C/ CINCO CENTAVOS' is explicitly written. The bottom margin includes what appears to be a printer's mark: 'QUAYLE & SON CORR NEW YORK.' The perforations are consistent and even on the visible edges. The stamp appears to be in unfranked condition, suggesting it is unused. There are no obvious signs of wear, tears, or significant creases, and the corners seem sharp. The print quality is fine, with clear details in the portraits and text, indicating good craftsmanship for its era.

I have examined the provided image of the Ecuador 5 Centavos Bicentenario La Condamine Stamp. Based on visual assessment, the stamp appears to be in very fine to extremely fine unmounted mint condition. The perforations are clean and intact, the centering is good for its era, and there are no visible faults such as tears, creases, or thins. The print quality is clear, and the design elements are well-defined. The 'QUAYLE & SON CORR NEW YORK' imprint is clearly visible, which is typical for stamps of this period from this printer. This stamp, Scott #375, commemorates the bicentennial of La Condamine's mission. While historically interesting, it is not considered rare. Such issues from Ecuador in unmounted mint condition typically trade at modest prices. Current market conditions show a steady, but not high, demand for this specific stamp. Comparables from online auction sites and dealer inventories for similar La Condamine issues in equivalent condition suggest a retail price range. Factors impacting value positively include its apparent unmounted mint status and the excellent preservation of the paper and print. The absence of faults is also a strong value contributor. However, its commonality prevents it from achieving a high value. It is important to note the limitations of appraising from an image alone. While the stamp appears genuine, full authentication would require in-person examination to verify paper type, watermark (if any), gum condition, and the absence of hidden faults or repairs. Microscopic examination could confirm print details. Provenance documentation, though not typically extensive for stamps of this value, would further confirm authenticity and history.
