Silver Denier (not authenticated)

The item is a small, circular silver coin housed within a standard square paper coin holder, secured with staples at the four cardinal directions. The visible side of the coin displays a detailed medieval-style iconography featuring a central cross design enclosed within a beaded circular border, surrounded by partially legible lettering or mint marks stamped along the outer rim. The metal exhibits a toned silvery-grey coloration with scattered darker areas of patina and minor surface wear consistent with age and historical circulation, though its true metallic composition remains unverified by physical testing. The owner's notes state an unverified user-attributed identification as a 'French Silver Denier 887-888 AD'. Furthermore, handwritten text is present on the outside of the coin holder, with 'FRANCE' written in red ink at the upper left corner and '887-898' written in black ink at the lower right corner; this external writing represents unverified context and does not constitute a manufacturer's mark or proof of authenticity. The identification in the name is based solely on the visual appearance of a medieval hammered silver denier coin style, with no definitive maker's mark or date directly confirmed by inspection.

Based on the provided image, I observe a small, circular, silver-colored hammered coin housed in a standard cardboard coin holder. The visible side features a central cross enclosed within a beaded border, which is highly characteristic of medieval European coinage. Per the user submission, this piece is identified as a French Silver Denier from 887-888 AD, and the holder bears handwritten notes stating 'FRANCE' and '887-898'. I must treat this attribution strictly as a working hypothesis, as I cannot verify the metallic composition, weight, or exact mint marks from a photograph alone. The visible toning and minor edge wear appear consistent with historical circulation, but physical inspection by a numismatic specialist would be required to weigh the coin, check for known die matches, and properly assess its origin. If the user's attribution is correct, comparable late 9th-century Carolingian or French medieval silver deniers typically sell in the $150 to $350 range, highly dependent on the specific ruler, mint clarity, and overall condition. However, if physical examination reveals this to be a later reproduction, replica, or misattributed copy, the numismatic value would drop significantly, likely to under $10. The estimate provided reflects the value of an item of this type assuming the historical attribution is accurate.
