AI Appraisal Estimate

This is a matching set of six (6) clear glass drinking tumblers, likely dating from the mid-20th century (circa 1950s-1960s). Each glass features a classic flared or conical silhouette with a weighted base for stability. The primary decorative element is a series of delicate, wheel-etched or wheel-cut 'starburst' or 'atomic star' motifs scattered across the upper body of the vessels. These stars consist of a central point with light, radiating lines of varying lengths, a hallmark design of the Mid-Century Modern aesthetic. The glasses appear to be made of thin-walled soda-lime glass, exhibiting high clarity through the body. In terms of condition, the items show indicators of prior use; notably, several glasses display small chips or 'flea bites' along the top rims, which is a common point of failure for glassware of this vintage. White adhesive residue or price stickers are visible on the interior bases of several pieces, suggesting a recent secondary-market acquisition. There are no visible maker's marks or signatures in the provided image, though the style is reminiscent of patterns produced by companies such as Libbey or Federal Glass. The craftsmanship is consistent with mass-produced tableware intended for home entertaining during the post-war era.

I have examined the provided images of this set of six (6) mid-century starburst etched tumblers. Based on the flared silhouette, weighted base, and whimsical wheel-etched 'atomic' motifs, I attribute these to the mid-1950s to early-1960s. While similar to Libbey’s 'Hoskins' or Federal Glass patterns, the lack of a 'script L' or 'F' hallmark suggests these may be from a smaller contemporary competitor or a non-branded retail line. The market for Mid-Century Modern (MCM) barware remains active, driven by its nostalgic appeal and functional use. However, condition is the primary driver of value in vintage glassware. My examination reveals multiple 'flea bites' and small chips along the rims. In the secondary market, glassware is typically graded as 'collector quality' only if the rims are smooth; these defects significantly diminish the value, as they pose a safety risk for use and deter high-end collectors. The presence of adhesive residue indicates a recent thrift or estate sale origin, common for these items. Comparables for pristine sets of six typically reach $85–$120. Given the noted damage, this set is valued at a 'utility' or 'display' price point. A physical inspection would be required to confirm the presence of any internal 'sickness' (cloudiness) or stress fractures not visible in photographs. To fully authenticate the manufacturer, I would need to compare the specific etch pattern and glass weight against a physical manufacturer catalog. Furthermore, fluorescence testing under UV light could reveal the chemical composition of the glass to confirm the production era.
