Pressed glass coaster with metal rim

This object is a circular beverage coaster featuring a clear glass body encased in a rounded metal rim. The glass center is decorated with a pressed or molded starburst pattern consisting of approximately twenty-four radiating petals around a central ring, further bisected by six structural ridges that reach the outer edge. The metal rim, which appears to be silver-toned, exhibits a polished finish consistent with chrome plating, stainless steel, or possibly silver plate, though no hallmarks are visible to verify the specific material. From the top-down perspective, the coaster appears to be in fair to good condition, showing some surface scratches on the glass and minor oxidation or dark spots on the metallic rim, typical of light domestic use. The design is stylistically consistent with mid-20th-century barware. Because no maker's mark, stamp, or manufacturer's label is discernible in the provided image, this identification is based on visual characteristics and the item's common functional form. Physical inspection would be required to identify the specific metal alloy or to determine if any branding is located on the underside.

Based on the image provided, I have evaluated this circular pressed glass coaster. From what I can see, the item features a starburst-patterned glass center held by a metal rim. While the metal exhibits slight oxidation and the glass shows minor surface wear, the overall condition appears consistent with light domestic use. I cannot verify from a photo the specific composition of the metal rim, as it could be chrome-plated steel, stainless steel, or silver plate; the absence of visible hallmarks suggests a mass-produced mid-20th-century origin rather than a high-end luxury manufacturer. My value estimate is based on the item being a generic example of vintage barware. The current market for individual coasters of this type is modest, as they are typically sought in sets of four, six, or eight. If this piece were part of a larger, branded set by a known manufacturer like Farberware or Frank M. Whiting (assuming sterling rims), the value would increase significantly. However, without a maker's mark or hallmark to confirm such an attribution, the value reflects its utility and decorative appeal. To confirm its identification and potential value, a physical inspection would be required to test the metal's purity and check for hidden stamps on the underside. Should this item be identified as a contemporary reproduction or a common plated variety rather than a mid-century piece with a precious metal rim, its value would likely remain at the lower end of the provided range. Market demand for single, unbranded barware items is generally limited to collectors seeking replacements for existing sets.
