Brass keychain with coin-like pendant

This item is a vintage-style brass keychain featuring a circular ring connected via a short, articulated snake chain to a circular medallion pendant. The entire piece is rendered in a metallic brass or base metal alloy with an aged, patinated gold-tone finish showing visible wear, tarnish, and surface discoloration consistent with age and handling. The pendant features a textured background of woven or basket-weave patterns, centered upon which is a square frame containing raised characters or symbols resembling East Asian calligraphy or script. The construction includes standard mechanical jump rings and a spring-loaded or hinged keyring mechanism at the top. There is no clearly legible maker's mark, hallmark, or stamped brand directly visible in the image to verify manufacturer or precise origin. The identification of this object is strictly visual, based on the observed hardware style, pendant design, and metal characteristics, and remains entirely unauthenticated.

Based on what I can see in the photograph, this is a vintage-style brass keychain featuring a snake chain and a circular medallion pendant with East Asian-style calligraphic symbols. I cannot verify from a photo the exact metal composition, age, or manufacturing origin, as there is no clearly legible maker's mark or hallmark visible. The piece displays an aged, patinated gold-tone finish with visible surface wear and tarnish. Assuming the item is a vintage mid-20th-century decorative accessory of this specific style, it would typically trade in the $30 to $60 range within the secondary vintage accessories market, driven by general interest in retro brass trinkets. However, I would need physical inspection to confirm the weight, true metal content, and construction quality. Because this item lacks clear authentication or maker attribution, this value is estimated conditionally. If physical examination reveals the piece to be a modern reproduction, mass-market replica, or purely 'in the style of' vintage novelty items rather than a period piece, the value would likely decrease to the $10-$20 range. To confirm authenticity and refine this estimate, an in-person examination by a decorative arts expert or specialist in vintage hardware would be required, along with potential metallurgical testing.
