AI Appraisal Estimate

This is a cohesive set of four matching circular drink coasters, likely dating from the mid-20th century (circa 1950s-1960s). Each coaster is meticulously crafted from pressed clear lead crystal glass, featuring a distinctive deeply molded starburst or radial sunburst pattern radiating from the center to the inner edge. This pressed design provides both aesthetic appeal and a functional textured surface to prevent glassware from suctioning to the coaster. The outer circumference of each coaster is finished with a hand-applied gold leaf or metallic gilt rim, which adds a touch of Mid-Century Modern elegance. Physically, they appear to be approximately 3 to 3.5 inches in diameter with a shallow raised lip to contain condensation. Regarding condition, the glass remains remarkably clear without visible chips or heavy scratching; however, there is noticeable age-related wear to the gold finish. The gilding shows typical thinning and some loss around the edges, consistent with handling and cleaning over several decades. While no maker's marks are visible in the photograph, the style and execution are characteristic of quality manufacturers from the period, such as Federal Glass or various European glassworks. The craftsmanship is evident in the sharpness of the radial facets and the uniform thickness of the glass walls.

I have conducted a visual examination of the Vintage Crystal Sunburst Glass Coasters. The set reflects the quintessential Mid-Century Modern aesthetic, likely produced between 1950 and 1965. The pressed starburst pattern is sharp, suggesting high-quality molds, while the hand-applied gold rims elevate the set from utilitarian to formal barware. My inspection reveals the glass is in excellent condition, devoid of the clouding or 'sickness' often seen in vintage lead crystal. However, the moderate thinning and loss of the gold gilt on the rims—typical of items subjected to repeated hand-washing—is the primary detractor from a premium valuation. The market for Mid-Century barware remains steady, particularly for 'Mad Men' era glassware. Comparable sets of four from manufacturers like Federal Glass or Indiana Glass typically sell in the $30-$50 range, while verified high-end European sets can fetch upwards of $80. The current appraised value accounts for the lack of a manufacturer's mark and the visible wear to the gilding, which prevents this set from reaching 'mint' collectors' pricing. Limitations of Image-Based Appraisal: A definitive authentication is limited by the inability to perform a physical 'ring test' for lead content or to inspect for micro-etchings under UV light that might identify the maker. To finalize this appraisal, I would require an in-person inspection to verify the tactile quality of the glass facets and check for 'flea bites' along the rim. Documentation of original packaging or a purchase receipt from the period would also enhance the provenance and potentially increase the valuation. This estimate assumes no structural cracks or deep gouges are hidden by photographic lighting.
