Mid-century style silver overlay glass tumbler

This item is a small, hand-sized tumbler or drinking glass featuring a translucent light blue glass body. It is decorated with a metallic silver-colored overlay that depicts a stylized, abstract bird motif, which appears consistent with Pacific Northwest Indigenous art styles or mid-20th-century modern interpretations of folk art. The metal overlay encircles the rim and forms the central graphic. Upon physical inspection of the image, the rim bears small stamped markings that appear to include the word 'STERLING' and a maker's mark consisting of a 'G' surrounding an 'S' inside a shield shape. This mark is stylistically consistent with the Silver City Glass Co. of Meriden, Connecticut, though this is a hypothesis subject to physical verification. The metal displays heavy tarnish with a dark, iridescent patina ranging from brownish to purple-blue hues. There is a visible crack appearing through the head of the silver bird figure, suggesting a possible fracture in the glass or a break in the metal overlay. Overall, the piece reflects a design aesthetic from the mid-20th century, approximately 1950s-1960s, though the exact date cannot be established from a photograph alone.

Based on my visual analysis of the provided image, I have examined this mid-century style silver overlay tumbler. The glass exhibits a translucent blue hue, decorated with an abstract bird motif. While I can see markings that appear consistent with 'STERLING' and a maker's mark associated with the Silver City Glass Co., I cannot verify these stamps from a photograph alone; physical inspection is required to ensure they are not spurious or misread. The value estimate assumes the hypothesis that the overlay is genuine silver on a mid-20th-century glass body. However, the visible crack through the bird's head significantly impacts the value, as condition is a primary driver for collectors of glass and silver overlay. Market demand for mid-century cocktail ware remains steady, but damaged pieces often see a 50-70% reduction in interest compared to pristine examples. This estimate reflects the assumed attribution; if the piece were determined to be a later reproduction or if the 'sterling' mark is found to be inaccurate upon testing, the value would likely drop to a decorative range of $10.00 - $20.00. To reach a more certain conclusion, an in-person examination by a specialist is necessary to perform a silver acid test, verify the hallmark stamps under magnification, and assess the depth of the glass fracture. The current valuation is based on general market behavior for similar silver-overlay glassware found in secondary markets.
