AI Appraisal Estimate

This item is a clear, elegant glass stemware piece, specifically a wide-bowl coupe typically used for champagne or tall sherbet service. The glass features a paneled, optic-style bowl with a flared rim, supported by a short, decorative pressed stem with an ornate knob or 'wafer' detail. The most striking element is the delicate floral and foliate wheel-etched or sandblasted design that wraps around the exterior of the bowl, depicting leafy sprays and clusters of small blossoms with fine linework. The glass exhibits high clarity and a thin, delicate rim indicative of quality mid-20th-century production, likely dating from the 1930s to 1950s Depression Glass or 'Elegant Glass' era. The construction shows a multi-part mold process for the stem joined to a blown bowl. No visible maker's marks or signatures are apparent in the image, which is common for companies like Cambridge, Fostoria, or Heisey. The condition appears excellent with no visible chips, cracks, or significant clouding, though some minor light surface scratches from age and use may be present upon physical inspection. The craftsmanship is refined, characteristic of American tableware manufacturers of the mid-century period, designed for formal dining and entertainment.

Based on my visual examination of the provided documentation, I have assessed this piece as a fine example of American 'Elegant Glass' from the Depression-era (circa 1930s-1940s). The item exhibits the characteristic high-lead content and clarity associated with top-tier manufacturers of the period, such as Fostoria, Heisey, or Cambridge. The floral wheel-etched motif and optic bowl paneling suggest a refined production process typical of mid-century formal service. The condition appears to be excellent, notably lacking the ‘glass sickness’ (clouding) or rim chips that often plague vintage stemware. The current market for glass coupes has seen a resurgence due to the popularity of craft cocktails; however, values are tempered by the high volume of production during this era. Comparables for single unbranded stems of this quality typically realize between $15 and $30 at retail. The value is maximized when presented as a set of 4, 6, or 8. The lack of a visible maker’s mark is standard for this category, as many manufacturers used paper labels that were removed by the original owners. Limitations: This appraisal is based solely on digital images. Without physical handling, I cannot verify the resonance (the 'ring') of the glass or detect microscopic flea bites along the base. Full authentication would require an in-person inspection to verify the mold seams and a UV light test to check for the manganese or uranium glow characteristic of specific glass recipes of the 1930s. Provenance documentation or original catalog matching would further solidify the attribution to a specific glass house.
