AI Appraisal Estimate

This is a commemorative souvenir card or maximum card issued for the IV Semana Popular Filatélica y Numismática (4th Popular Philatelic and Numismatic Week) held in Madrid, Spain. The item is printed on an off-white or cream-colored cardstock of rectangular orientation. It features a blue monochrome architectural sketch on the left side, likely depicting a historic Spanish building. The card is embellished with two postage stamps: a green 30-PTA stamp depicting a historical figure in a library setting and a purple 25-PTA stamp featuring King Alfonso XII adorned with fleur-de-lis symbols. Both stamps are marked with special commemorative circular cancellations dated between March 27 and April 4, 1.982. The text is printed in a clean, sans-serif black font along the right and bottom edges. The condition appears excellent with crisp corners, though there is a very slight notch or manufacturing artifact on the bottom right corner. The ink remains vibrant, and the cancellation marks are clear and legible, indicating high collectible quality. This philatelic item serves as a philatelic record of a specific 1980s numismatic event in Madrid.

Upon visual examination of this IV Semana Popular Filatélica y Numismática souvenir card from 1982, I find the item to be in 'Extra Fine' condition. The cardstock maintains its original cream luster without significant foxing or toning. The stamps, including the 30-PTA library series and the 25-PTA Alfonso XII issue, are centered well and exhibit vibrant coloration. The commemorative cancellations are applied with high clarity, which is a key driver for value in maximum cards and souvenir sheets. From a market perspective, Spanish numismatic event souvenirs from the early 1980s were produced in relatively large quantities for collectors, which limits their scarcity. Similar philatelic souvenirs from this era typically trade in the low double-digit range. The primary value factor here is the specific event tie-in and the thematic appeal to Spanish royalty and library topical collectors. Rarity is considered low, though findability in this crisp condition provides a slight premium over weathered examples. A significant limitation of this digital appraisal is the inability to verify the paper's watermark or the authenticity of the cancellation ink through chemical or ultraviolet testing. For a definitive authentication, I would require an in-person physical inspection to examine the card's fiber structure, verify the lack of adhesive residue behind the stamps, and confirm the cancellations are not modern reprints. Provenance documentation from the 1982 Madrid exhibition would further solidify its historical legitimacy.
