AI Appraisal Estimate

This item is a small, ornate mug or cup crafted from pressed glass. The glass appears to be a very deep, dark color—either black-amethyst (which shows purple when held to light) or a dense ruby red. The exterior features a highly tactile, molded diamond-point or hobnail pattern arranged in geometric and circular motifs, appearing stylistically consistent with late 19th-century Victorian or mid-20th-century Early American Preserved Glass (EAPG) revivals. The cup possesses a distinctive C-shaped handle with cross-hatched circular medallions at the terminals. It rests on a multi-sided pedal or hexagonal base with a serrated or 'zipper' edge at the bottom. No maker's marks or logos are visible in the photograph; therefore, specific attribution to manufacturers like Imperial Glass or Westmoreland remains a hypothesis based on stylistic similarities. The craftsmanship shows typical seams from a multi-part mold. The surface appears to be in well-maintained condition with a high gloss, showing no obvious chips or cracks in the provided view, though some light surface dust is present. All identifications are subject to in-person inspection of light translucency and potential base marks.

Based on the provided imagery, I have examined this pressed glass mug featuring an intricate diamond-point pattern and a multi-sided pedal base. The dark coloration suggests a working hypothesis of black-amethyst or deep ruby glass, though I cannot verify the exact hue or translucency without holding the piece to a direct light source. The molding appears consistent with Early American Pattern Glass (EAPG) styles from the late 19th century or, more likely, mid-20th-century revivals produced by companies such as Imperial Glass or Westmoreland. While the piece bears characteristics associated with these manufacturers, the absence of a visible trademark in the photo means any specific attribution remains a hypothesis. My value estimate is based on the item being a mid-century production in excellent condition. If physical inspection were to reveal a verified manufacturer's mark, such as the Imperial 'IG' or Westmoreland's 'WG', the value might sit at the higher end of the range. Conversely, if the piece is an unattributed modern reproduction or contains undisclosed chips to the sharp hobnail points, the value would likely fall below $15. The market for mid-century colored glass remains stable among niche collectors, though demand is most consistent for pieces with documented provenance or clear catalog matches. To reach a more formal conclusion, an in-person examination is required to check for 'straw marks,' mold wear, and specific base wear patterns that differentiate vintage glass from modern copies. Scientific testing of the glass composition or a review of original manufacturer catalogs would be necessary to validate any specific historical attribution.
