AI Appraisal Estimate

This is a large-format clear glass cup or mug, potentially used for coffee or soup, featuring intricate embossed decorative elements. The piece is constructed from thick, pressed soda-lime glass, characterized by its substantial weight and durability. The exterior body is adorned with a repetitive pattern of circular sunburst or floral medallions, framed by bead-like textures and rows of scalloped or petal-shaped indentations. A series of small vertical ridges lines the upper rim, while the base features a complementary beaded border. The handle is a simple, clear C-shaped loop, seamlessly integrated into the side of the vessel. The style is reminiscent of early to mid-20th-century American pressed glass (Early American Pattern Glass) but is likely a contemporary reproduction or modern houseware item designed with vintage aesthetics. The glass exhibits high clarity with no visible chips, cracks, or significant clouding, though there is a small yellowish droplet of residue on the handle. The absence of visible maker's marks or pontil scars suggests modern industrial manufacturing via a mold process.

Based on my visual examination of this large-format clear glass medallion cup, I have determined it to be a contemporary piece of pressed glassware produced using modern industrial mold processes. The item mimics the 'Early American Pattern Glass' (EAPG) style, specifically drawing inspiration from sunburst and floral medallion motifs popular in the late 19th and early 20th centuries. However, the thickness of the glass, the seamless integration of the C-shaped handle, and the high clarity of the soda-lime composition point toward a modern mass-market origin, likely sold through retail chains specialising in vintage-inspired housewares. The condition appears excellent, with the glass showing no signs of 'sickness' (cloudiness) or significant chips. I did observe a small yellowish droplet on the handle, which appears to be organic residue or adhesive that could be easily cleaned. The absence of a pontil mark or maker’s mark confirms it is a machine-molded piece rather than hand-blown or early artisanal glass. Because these items are produced in high volumes, rarity is negligible, and demand is driven by utility and decorative appeal rather than collector value. Market comparables for modern EAPG-style mugs typically sell in the $10 to $18 range at secondary markets or vintage-style retailers. A significant limitation of this appraisal is the transition from digital image to physical reality; I cannot verify the presence of micro-scratches or mold seams that would further clarify the manufacturer. To provide a definitive authentication, I would require an in-person inspection to evaluate the 'ring' of the glass (checking for lead content) and a search for etched acid marks on the base. No scientific testing is recommended given the item's modern aesthetic and low market value.
