Coin Pendant with Double-Headed Eagle

This item is a circular coin or coin-like medallion mounted as a pendant. The central feature is a relief of a Double-Headed Eagle, a heraldic symbol traditionally associated with various historical empires, most notably the Russian Empire (Romanov Dynasty) or the Byzantine and Austro-Hungarian Empires. The piece is crafted from a dark-toned metallic alloy, possibly silver with a heavy aged patina or a base copper-nickel alloy that has oxidized over time. The coin is encased in a smooth, metallic bezel frame that secures the edges without obscuring the face. At the top of the frame, there is a small cylindrical mounting point attached to a jump ring, through which a larger black cord or wire loop is threaded for wearing as a necklace. Physically, the item appears to be roughly 20-30mm in diameter. The condition shows significant signs of age and wear; the relief of the eagle is somewhat softened by friction, and the metal surface exhibits dark oxidation and localized pitting. There are no clearly legible inscriptions or dates visible in the image due to the level of surface wear and photographic resolution, but the style suggests a late 19th or early 20th-century origin. The craftsmanship is functional, focusing on the conversion of a piece of currency or a commemorative token into a wearable memento.

I have examined the provided image of the pendant featuring a double-headed eagle medallion. The item appears to be a 19th-century circulated coin, likely of Russian or Central European origin, repurposed into jewelry. The condition is Fair to Good (VG); the metal shows significant circulation wear, softened relief on the eagle crest, and heavy oxidation consistent with a silver alloy or patinated base metal. The bezel is a simple functional mount rather than high-end goldsmithing. The market for numismatic jewelry depends heavily on the rarity of the host coin and the metal content. Given the level of wear and the lack of legible mint marks or dates, the value resides mostly in its aesthetic as a historical memento rather than as a high-grade collector's coin. Similar pieces often sell at flea markets and online vintage auctions in this price bracket. Significantly, I cannot determine the exact metal composition or the authenticity of the host coin from this image alone. A full valuation would require an in-person acid or XRF test to confirm if the material is .800/.900 silver or a pewter/copper-nickel alloy. Furthermore, a physical inspection would be needed to verify if the coin is a period-authentic striking or a modern cast souvenir replica. Provenance documentation regarding its conversion into jewelry would also clarify its historical context.
