AI Appraisal Estimate

This is a used vertical postage due stamp issued during the Federal People's Republic of Yugoslavia (F.N.R. Jugoslavija) era, likely dating from the early 1950s. The stamp is printed in a distinct orange or vermilion ink on off-white paper and features a denomination of 10 Dinara. The central design depicts five crossed torches held aloft against the backdrop of a large five-pointed star, symbolizing the unity of the Yugoslav republics. The inscription 'PORTO' identifies it as a postage due issue. It possesses standard perforations on all four sides, though some show light wear and irregular separation. A prominent black circular date stamp (CDS) cancellation is visible, indicating postal usage; this cancellation slightly obscures parts of the central motif and the text. The paper shows natural aging and minor toning, common for its era. The printing quality is characteristic of state-produced philatelic materials of the period, displaying clear typography in both Latin and Cyrillic scripts. There are no major tears or thins apparent in the photograph, but the bottom-right corner reveals a slight bluntness. This piece serves as a physical record of the post-WWII socialist period in the Balkans.

I have carefully examined the provided image of the Yugoslavia 10 Dinara Postage Due stamp. Authenticity is consistent with the flat-plate printing methods of the state-run mints of the early 1950s. The 'PORTO' inscription and the five-torch star motif represent a common issue from the socialist era. The condition of this specific specimen is 'Used/Fine' with a standard circular date stamp (CDS) cancellation. While the colors remain vibrant, the slight blunting of the bottom-right corner and irregular perforations are typical for utility stamps of this period. In terms of market value, these specific issues were printed in massive quantities for administrative use and are readily available to collectors today. They lack the rarity required to command a premium, often retailing as part of bulk lots or 'penny' boxes. The primary value is historical rather than financial. Please note that while the visual characteristics align with genuine issues, a definitive assessment of paper thickness, watermark direction (if any), and the chemical composition of the ink would require a physical examination under high magnification and UV light. For a full certificate of authenticity, I would need to inspect the gum on the reverse (if applicable) and check for hidden thins or repairs that are not visible through a standard photograph.
