Gold-filled and carved floral brooch, attributed to W.R. Cobb Co. (not authenticated)

This is a vintage brooch featuring a floral motif, likely crafted from gold-filled metal and a carved organic or celluloid material representing a white flower bloom. The physical construction includes three curved stem-like wires bound together, attached to two etched leaf elements and a single carved flower head. The reverse displays a pin-stem mechanism with a traditional rolling-catch clasp, showing patina, mild tarnish, and surface wear consistent with age and previous use. Notable markings include a visible hallmark stamp on one of the leaves reading '1/20 12K G.F.' alongside a maker's mark consisting of the letters 'W.R.C.' or similar initials, which suggests the presence of a W.R. Cobb Co. mark (unverified). The style period points toward mid-20th-century costume jewelry craftsmanship. The identification of the maker rests primarily on the visible stamped hallmark on the leaf component, while the overall age and materials remain unverified.

Based on what I can see in the provided image, this vintage brooch features a carved floral element and gold-filled components with a rolling-catch clasp, displaying a stamp that appears consistent with the W.R. Cobb Co. mark and a '1/20 12K G.F.' designation. However, I cannot verify the exact metal composition, material of the carved flower, or the absolute legitimacy of the hallmark from a photograph alone. A physical inspection would be needed to confirm these details. The estimated value range of $75 to $150 assumes that the attribution is correct and the gold-filled elements and hallmark are as they appear. Mid-20th-century costume and semi-fine floral jewelry of this type generally appeals to collectors of vintage accessories, though market demand fluctuates based on wearable condition and current trends. If physical examination reveals that the piece is a later reproduction, replica, copy, or merely made in the style of the period without the attributed maker's connection, the market value would likely decrease to the $25-$50 range. To confirm authenticity and solidify the attribution, an in-person examination by a qualified expert, physical hallmark verification, and potentially metal testing would be necessary.
