AI Appraisal Estimate

This is a vintage circular glass plate featuring an intense lime or 'apple' green coloration, which indicates the likely presence of uranium dioxide as a colorant, often causing it to glow under UV light. The plate is decorated with a complex pressed glass design known as the 'Beaded Shell' pattern, characterized by concentric textured rings at the center that transition into a series of uniform, narrow radial flutes or ribs extending to the rim. Measuring approximately 9 to 10 inches in diameter, the piece exhibits high-quality craftsmanship typical of the early 20th-century American pressed glass industry, specifically associated with manufacturers like Dugan or Diamond Glass-Ware Co. circa 1910-1920. The glass appears to have a semi-translucent quality with a glossy fire-polished finish. Condition-wise, the plate surfaces appear well-preserved with no visible chips, cracks, or heavy scratching on the face, though minor shelf wear to the base and microscopic production bubbles (seeds) common for this era may be present. The piece is displayed upright on a black tripod stand, highlighting its geometric symmetry and vibrant saturation. Its mid-century modern aesthetic appeal makes it a cross-collectible piece for both Depression-era glass enthusiasts and modern decor aficionados.

Based on my visual examination of the provided imagery, I have assessed this 10-inch 'Beaded Shell' pattern plate in Nile Green (Uranium) glass. The piece is characteristic of the Dugan/Diamond Glass Company, dating between 1910 and 1920. The pressing is crisp, indicating a relatively early run from the mold, and the coloration is consistent with the 'Apple Green' or 'Nile Green' palette highly sought after by vaseline and uranium glass collectors. Based on the photos, the item appears to be in 'Near Mint' condition with a high-gloss fire-polished finish and no evidence of significant flea bites or annealing cracks. The market for early 20th-century pressed glass remains stable but specialized. Uranium glass has seen an uptick in demand due to 'glow-responsive' collecting trends. This specific pattern is less common than the standard 'Beaded Shell' bowls or nappies, which adds a slight rarity premium. Comparables for Dugan plates in similar green shades generally realize between $40 and $70 at specialized glass auctions or online platforms. Note that this appraisal is based on photographic evidence. I cannot definitively verify the uranium content without a 365nm longitudinal UV light test, though the visual hue is highly diagnostic. A physical inspection would be required to rule out contemporary reproductions or subtle ground-down chips on the rim. Final authentication would rely on feeling for 'straw marks' versus modern scratches and confirming the weight and resonance of the piece. Provenance documentation regarding its history within a specific collection would further solidify its market position.
