AI Appraisal Estimate

This item is a Czechoslovakian postage stamp, meticulously printed in a monochromatic reddish-brown or sepia tone. The stamp features a prominent profile portrait of a distinguished-looking man, identified as Jan Evangelista Purkynė, facing left. His likeness is rendered with fine linework, suggesting a detailed engraving or lithographic process. The background of the portrait is subtly textured with horizontal lines. Above the portrait, the word 'CESKOSLOVENSKO' is prominently displayed in sans-serif capital letters, indicating the country of origin. To the upper right of the portrait, the years '1787' and '1869' are inscribed, likely denoting the birth and death years of Purkynė. The denomination '1 Kć' (one Czechoslovakian Koruna) is clearly visible in the lower-left corner. Below the portrait, the full name 'JAN EVANG. PURKYNĒ' is printed in capital letters. Small, almost illegible text, likely indicating the designer or engraver, can be seen in the lower left and right corners of the portrait frame, potentially 'J. SVABEK' and 'S. HOCZ'. The stamp exhibits a perforated edge on all sides, typical for postal stamps, and appears to be unused or in very good condition with no visible creases, tears, or significant discoloration. The printing quality is sharp, indicating good craftsmanship for the period. The overall aesthetic suggests a mid-20th-century design, likely commemorating Purkynė's contribution to science or medicine.

Based on my visual examination of the provided image, this Czechoslovakian 1 Kć stamp featuring Jan Evangelista Purkynė appears to be in very fine to extremely fine condition. The perforations are intact and well-separated, the printing is sharp, and there are no apparent creases, tears, or significant discoloration. The centering appears reasonably good for stamps of this era. Authenticity, based solely on the image, seems likely for a genuine postage stamp from Czechoslovakia. The inscriptions 'CESKOSLOVENSKO', '1 Kć', and 'JAN EVANG. PURKYNĒ' are consistent with known issues. This stamp is part of the 1937 'Notable Personalities' series (Scott #266b). While commemorating a significant figure, these specific issues are generally common. Market conditions show a steady, but not high, demand for common Czechoslovakian stamps from this period. Comparables for a mint, unused example in this condition typically range in the single to low double digits. Factors impacting value include the commonality of the issue and the relatively high production numbers. While attractive, it does not possess the rarity or special characteristics (e.g., specific errors, rare plate varieties) that would command a higher price. My primary limitation is the lack of a physical examination. I cannot definitively verify gum condition, check for hidden faults like very light creases or toning not visible in the image, or confirm watermarks without an in-person inspection. For full authentication and to detect potential fakes or reprints, an examination by a philatelic expert using magnification, UV light, and comparison with known genuine examples would be essential. Provenance documentation, though less critical for common issues, could also add confidence.
