AI Appraisal Estimate

This item is an opaque white milk glass butter dish consisting of a rectangular domed lid and a matching underplate with a decorative border. The lid features vertical ribbing on its sides and what appears to be a floral or harvest-themed relief pattern on the top surface, though the details are softened by the material's opacity. The underplate features a scalloped or beaded edge, a motif stylistically consistent with the 'Beaded Edge' pattern produced by the Westmoreland Glass Company during the mid-20th century. The glass exhibits a smooth, semi-glossy finish typical of pressed milk glass. At the time of the photograph, the lid is secured to the base with a strip of translucent tape, potentially for transport or storage. No maker's marks or logos are visible in the provided image; therefore, the attribution to Westmoreland remains a stylistic hypothesis subject to in-person verification of a hallmark (such as an intertwined 'WG'). The item appears to be in good vintage condition with no immediate evidence of large cracks or deep chips visible from this angle, though milk glass of this era often displays minor factory shelf wear or small 'flea bite' nicks along the inner rims.

Based on my visual examination of the provided image, I have assessed this milk glass butter dish. The piece exhibits characteristics, such as the beaded scalloped edge and vertical ribbing, that are stylistically consistent with the Beaded Edge pattern typically associated with the Westmoreland Glass Company. However, I cannot verify the presence of a 'WG' mark or other manufacturer hallmarks from these photographs alone. This attribution remains a hypothesis that would require an in-person inspection to confirm through hallmark verification or mold-mark analysis. The value of $25–$45 reflects a typical market range for 20th-century pressed milk glass if the attribution to a known maker like Westmoreland holds true. From what I can see, the glass appears to be in good vintage condition, though the presence of tape suggests a need to check for hidden chips or residue that might impact the surface finish. In the current secondary market, there is a steady but modest demand for mid-century American milk glass. If the item were determined to be a later reproduction or a generic piece 'in the style of' Westmoreland without a specific manufacturer's pedigree, the value would likely decrease to the $10–$15 range. To reach a more certain valuation, one would need to physically examine the rim for 'flea bites,' verify the translucency of the glass under light, and search for documented provenance. A final determination of value is contingent upon the piece being free of structural damage that is not visible in the current photo.
