AI Appraisal Estimate

This is a vintage Norwegian souvenir brooch crafted from 830S silver, featuring a design based on historical motifs from the medieval period. The back of the pin is stamped with '830S', 'NORWAY', and the anchor maker's mark for the renowned goldsmith Hans Myhre. Additionally, it bears the inscription 'KOPI AV MOTIV FRA 1400 ÅRENE BRYGGEN/BERGEN', indicating the design is a copy of a motif found at the UNESCO-protected Bryggen wharf in Bergen dating back to the 1400s. Physically, the brooch features an openwork, cut-out design with scalloped edges and twin scroll-like flourishes at the top. The silver has developed a significant dark grey and gold-toned patina through oxidation, which highlights the age and texture of the piece. The construction includes a horizontal C-clasp hinge and pin assembly. The item shows signs of light surface scratches and minor tarnishing consistent with mid-20th-century vintage jewelry. The craftsmanship is typical of the high-quality Scandinavian silver production popular between 1940 and 1960. It serves as both a cultural artifact representing Bergen's Hansa-era history and a fine example of mid-century Norwegian silversmithing.

I have virtually examined this Norwegian 830S silver brooch, featuring the hallmark of Hans Myhre. The piece is an authentic example of mid-20th-century Scandinavian souvenir jewelry, specifically reproducing 15th-century motifs from the Bryggen wharf in Bergen. My inspection reveals a strong, naturally aged patina with gold and slate tones that emphasize the openwork design. The presence of the '830S' hallmark, anchor mark, and specific historical inscription confirms its origin and intended market as high-quality tourist silver from the 1940s-1960s. The condition appears commensurate with age; minor surface micro-abrasions and tarnish are visible, but the structural integrity of the C-clasp hinge remains intact. The current market for Norwegian silver is stable, with Hans Myhre being a well-collected name, though value for these common souvenir motifs is generally dictated by silver weight and design complexity rather than extreme rarity. Similar medieval-motif brooches consistently fetch between $60 and $100 in specialty vintage markets. It is important to note that while the hallmarks are consistent with authentic Myhre production, a final appraisal would require in-person verification of the pin's weight and a metal acid test to confirm the silver purity. Furthermore, I would recommend a physical inspection to ensure the hinge movement has not been repaired or replaced, which could affect collector value.
