AI Appraisal Estimate

Historical commemorative coin from Poland, minted in 1983 to celebrate the 300th anniversary of the Relief of Vienna (300 Lat Odsieczy Wiedeńskiej). The obverse shown features a detailed high-relief bust of King Jan III Sobieski facing forward, adorned in ornate 17th-century period armor including a prominent chain and mantle. The inscription '300 LAT ODSIECZY WIEDEŃSKIEJ' arcs over the top, while 'JAN III SOBIESKI 1674-1696' is etched at the bottom. This coin is typically struck in a copper-nickel (CuNi) alloy, presenting a cool silver-toned metallic finish with a matte or satin luster. The craftsmanship is of standard circulation-commemorative quality with clear, legible typography and intricate texture on the king's facial hair and armor. The surface exhibits a light natural patina with slight darkening around the recessed lettering and figures. Visible condition appears to be Extra Fine (XF) to About Uncirculated (AU), showing minimal surface contact marks, sharp edges, and no significant denting or deep scratching. The rim is well-defined and circular. This piece represents a significant moment in Polish numismatic history during the People's Republic era, honoring a national hero.

Upon visual examination of this 1983 Poland 50 Złotych commemorative coin featuring King Jan III Sobieski, I find the specimen to be in 'About Uncirculated' (AU) condition. The relief remains sharp, particularly in the detailed textures of the King's armor and facial features. This coin, struck in copper-nickel (CuNi) by the Mennica Warszawska (Warsaw Mint) with a mintage of approximately 2.5 million pieces, was a high-volume commemorative issue intended for wide circulation and collectors during the People's Republic of Poland era. The silver-toned metallic finish displays high-point luster consistent with its alloy composition, and the light patina suggests natural aging without chemical cleaning. The current market for later 20th-century Polish base-metal coinage is highly saturated; while Jan III Sobieski is a revered national hero, the high mintage volume limits its rarity and investment potential. Comparable sales on international numismatic platforms consistently place raw examples in this grade range within the $4 to $12 bracket. Factors such as deep scratches or signs of 'PVC haze' from poor storage would devalue the piece further, though none are visible here. Please note that while the coin appears authentic in design, weight, and strike characteristics, a definitive authentication requires physical testing. Image-based appraisal cannot confirm the exact weight (standard 11.7g), diameter (30.5mm), or metallic purity. A professional in-person inspection and comparison against a known reference sample would be necessary to rule out high-quality contemporary counterfeits, though the low intrinsic value of this specific issue makes such forgeries unlikely.
