AI Appraisal Estimate

This is a proof-quality silver commemorative medal issued by the Czech Mint (Česká mincovna) in 2017 to honor the legendary singer and dissident Marta Kubišová. The medal is struck from 31.1 grams (1 Troy ounce) of fine .999 silver, with a diameter of 37 mm and a milled edge. It is housed in a clear protective acrylic capsule and presented in a premium dark blue velvet-lined display box. The obverse features a modern, geometric design with a star and the name 'MARTA KUBIŠOVÁ' in bold lettering. The set includes an official Certificate of Authenticity (Certifikát pravosti) which features a personalized ink inscription and a signature, potentially from the artist or the subject, adding unique provenance. The certificate provides technical specifications including the author, Roman Shamilyan, and the engraver, Lubomír Lietava. With a limited mintage of only 1,000 pieces, this item is a high-craftsmanship numismatic collectible in excellent condition, showing no visible signs of wear or oxidation on the silver surface.

I have carefully examined the high-resolution images of the 2017 Marta Kubišová Czech Mint 1 oz Silver Commemorative Medal. The specimen appears to be in its original mint-state condition, exhibiting the 'proof' finish's characteristic mirror-like fields and frosted relief. I observe no signs of 'milk spots,' hairline scratches, or handling-induced tarnish (toning), which is vital for maintaining the premium over spot price for Czech Mint issues. The presentation packaging and Certificate of Authenticity appear consistent with official 2017 releases by Česká mincovna. From a numismatic standpoint, this medal benefits from two primary value drivers: its technical scarcity (limited mintage of 1,000) and the high cultural significance of Marta Kubišová in Central Europe. While silver spot price provides a baseline 'melt' value, the market for this specific medal is driven by collectors of the 'Slavík' (Nightingale) series. Current market conditions for recent Czech commemorative medals are stable, with higher demand within the EU market than in North America. The inclusion of a signed certificate significantly enhances the secondary market appeal, potentially adding a 20-30% premium over an unsigned set. Note: This appraisal is based on image analysis and cannot account for precise weight verification or silver purity testing (such as an XRF scan). For definitive authentication, an in-person inspection would be required to verify the signature’s ink depth and the medal’s exact edge characteristics. Under light magnification, I would also need to ensure no micro-abrasions were caused by previous removals from the capsule. Without physical examination, the authenticity of the signature must be considered 'attributed'.
