Vintage-style gold-tone tie tack with mother-of-pearl inlay and T-bar chain

This item appears to be a vintage-style tie tack or tie chain accessory. It features a square decorative face with a gold-tone metallic finish, textured cross-hatching, engraved flourishes in the corners, and a central circular inlay that is consistent in appearance with mother-of-pearl or white enamel. Attached to the back is a fine curb chain leading to a silver-tone or gold-tone cylindrical T-bar, designed to slip through a shirt buttonhole to secure a necktie in place. The metal composition is unverified from the photo alone and appears to be standard costume jewelry alloy, electroplated or polished. Light surface wear, minor scratching, and subtle discoloration on the metal surfaces are visible, consistent with age and gentle use. No clear maker's marks or hallmarks are visible in the provided image; therefore, any attribution to a specific manufacturer or exact manufacturing date remains speculative and subject to in-person verification.

Based on what I can see in the provided image, this item appears to be a vintage-style tie tack featuring a square gold-tone face with textured cross-hatching, corner flourishes, and a central mother-of-pearl or enamel inlay, complete with a T-bar chain attachment. I can't verify from a photo whether the metal is a base costume alloy or a precious metal, as no hallmarks or maker's marks are visible. A physical inspection, including testing the metal composition and inspecting under magnification, would be needed to confirm if it is solid gold, gold-filled, or simple electroplate. Assuming this is a standard vintage base-metal costume jewelry piece as its appearance suggests, the estimated fair market value is in the $15 to $30 range. This valuation is based on its decorative appeal, light surface wear consistent with age, and the general secondary market demand for mid-century men's fashion accessories. If an in-person examination were to reveal hallmarks indicating solid gold construction (such as 10k or 14k), the value would increase significantly based on the intrinsic melt value and collector interest, potentially reaching $75 to $150 or more depending on weight. Conversely, if it is a modern mass-produced reproduction or shows heavier wear upon closer inspection, the value would remain at the lower end of the $10 to $15 range. Demand for vintage tie accessories remains modest, primarily driven by niche menswear enthusiasts and vintage costume jewelry collectors.
