Yellow-metal-set pendant featuring a coin consistent with ancient Roman style

This item is a circular pendant consisting of a dark, weathered coin-like disc mounted in a smooth yellow-metal bezel. The central element appears to be a numismatic object, possibly bronze or another base metal, characterized by a heavy dark patina and surface degradation that obscures finer details. From the visible relief, the imagery is stylistically consistent with Roman imperial coinage, featuring what appears to be a profile head and faint circumferential lettering that is not clearly legible in the image. The coin is held in a modern-style polished mount with a simple bail at the top for suspension. The metal surrounding the coin has a luster consistent with gold-plated or solid gold construction, though no hallmarks or fineness stamps are visible to verify the metal's purity or composition. The coin itself shows significant signs of age, including pitting and edge wear, which is typical for items salvaged from archaeological contexts. The mounting appears to be in good condition with minor surface scratches. While the coin is consistent with ancient types, its age and origin remain unverified without physical examination, as modern replicas are common. The attribution to a specific era is based solely on stylistic profile indicators.

I have examined the digital image of the yellow-metal-set pendant featuring an ancient-style coin. Based on what I can see, the central element appears to be a numismatic object consistent in profile with Roman imperial coinage; however, I cannot verify from a photo whether this is an ancient artifact or a modern reproduction. The heavy patina and surface pitting observed are typical for archaeological finds but are also frequently replicated in cast copies. The metal mount exhibits a luster suggestive of gold, but without visible hallmarks or fineness stamps, I cannot determine the purity of the metal or whether it is solid gold or gold-plated. The value estimate of $250 to $650 is based on the hypothesis that the coin is an ancient bronze piece and the mount is of at least 14k gold. Markets for ancient-style jewelry remain stable, with demand driven by the aesthetic of 'wearable history.' However, should a physical inspection reveal the coin to be a modern replica or the mounting to be non-precious plated metal, the value would likely decrease to a decorative range of $20 to $75. To confirm the value, an in-person examination by a professional numismatist and a jeweler is required to perform metallurgical testing on the mount and verify the coin's strike characteristics and edge profile. Provenance documentation would also be necessary to establish legitimate transfer and age. This estimate reflects the current market for similar styles, but does not assert the origin of the materials.
