Ancient Roman coin pendant bezel-set in gold tone jewelry (unauthenticated)

This item is presented as a pendant featuring a metallic coin mounted within a yellow-toned metal bezel frame, suspended from a twisted rope-style chain necklace. The central coin exhibits a greenish-brown patina and displays a profile bust facing right, with visible circular Latin lettering and stamped text along the outer rim. The surrounding bezel and bail are polished and reflective, creating a strong contrast with the ancient appearance of the coin. At the top and bottom of the bezel frame, engraved or stamped text is visible, including uppercase lettering reading 'GORDIANO III' along the upper rim and numbers reading '238 - 244 D.C.' along the lower rim, which aligns with the historical reign of the Roman Emperor Gordian III. The owner's provided context identifies this as a 2000-year-old Roman coin, though this user-supplied claim is unauthenticated and requires professional verification. The overall construction suggests a modern jewelry mounting applied to an older or replica numismatic piece, displaying standard light surface wear and polish marks consistent with contemporary handling of mounted jewelry items.

Based on what I can see in the image, this piece features a metallic coin with a greenish-brown patina mounted in a polished yellow-toned metal bezel frame with a twisted rope-style chain necklace. The frame bears stamped text including 'GORDIANO III' and '238 - 244 D.C.', aligning with the reign of the Roman Emperor Gordian III. Per user submission, the owner identifies this as a 2000-year-old Roman coin. However, I can't verify from a photo whether the coin is an ancient artifact or a modern reproduction, replica, or tourist souvenir, nor can I confirm the precious metal content of the bezel and chain from visual inspection alone. Would need physical inspection to confirm material composition and numismatic status. The estimated value range of $350 to $600 assumes that the coin is an ancient piece and the mounting is crafted from solid gold or high-grade gold-filled materials. If physical testing reveals the item is a modern replica or made of base metal with gold-tone plating, the market value would drop significantly, likely falling into the $50 to $150 range primarily for the decorative jewelry mounting. Demand for ancient coins mounted in modern jewelry is a niche market, appealing to buyers who appreciate historical aesthetics. To confirm authenticity and establish a precise value, physical examination by a numismatic expert, assay testing for metal purity, and professional appraisal would be required.
