AI Appraisal Estimate

This is a vintage silver-plated wine goblet or stemmed chalice, specifically produced by the F.B. Rogers Silver Company and manufactured in Spain. The piece is constructed from a base metal, likely brass or copper, which has been plated with silver. Its silhouette features a tall, flared conical bowl that tapers down to a highly decorative cast stem. The stem is the defining feature, exhibiting a detailed grapevine or 'grape cluster' motif, a classic design element common in mid-to-late 20th-century barware. The item sits on a simple, circular pedestal base that provides stability. Regarding its condition, the goblet shows significant oxidation and heavy dark tarnish across the bowl and base, typical of vintage silver plate that has not been polished recently. There are visible areas where the silver plating appears to be thinning or worn (plate loss), especially around the base rim, revealing the darker base metal beneath. No structural dents or repairs are immediately apparent, but the surface shows general age-related pitting. The craftsmanship reflects a mass-produced but high-quality mid-century aesthetic, likely dating from the 1960s to the 1980s. The 'Spain' manufacture mark (indicated in the context but not visible in the photo) was a common origin for these specific heavy-gauge plated items distributed by F.B. Rogers.

Based on my examination of the provided imagery and technical description, I am identifying this piece as a vintage silver-plated wine goblet produced by F.B. Rogers Silver Co., manufactured in Spain during the late 20th century (c. 1960s-1980s). The grapevine motif on the stem is a hallmark of the company’s mid-century export line. Physically, the item exhibits significant tarnish and oxidation, with visible 'bleeding' of the base metal (likely brass) through the silver plating—a condition known as plate loss. This significantly impacts the aesthetic and dictates the current market value at the lower end of the spectrum. The market for mid-century silver plate is currently saturated; these items were mass-produced and lack the precious metal content of sterling silver, making them 'utility decorative' rather than high-investment antiques. Collectors typically prefer these in sets of six or eight; a solitary goblet with heavy patina is generally sold as a replacement part or a project piece for re-silvering. Limitations of this appraisal include the inability to inspect the underside for the 'Spain' stamp or verify the exact composition of the base metal beneath the plating. A professional cleaning would be required to rule out deeper pitting or permanent corrosion. For full authentication, an in-person examination of the hallmark stamp and a weight check would be necessary to ensure this is an authentic F.B. Rogers casting rather than a contemporary reproduction. No additional scientific testing is warranted given the mass-produced nature of the item.
