AI Appraisal Estimate

This is a two-piece covered butter dish crafted from translucent pink depression glass, a hallmark of American tableware from the late 1920s through the 1930s. The set consists of a square-shaped base plate with rounded corners and a circular, bell-shaped lid. The lid features a molded glass finial or knob for easy handling. Physically, the glass exhibits the characteristic delicate pink hue achieved through the addition of selenium or manganese. The construction is pressed glass, showing the typical mold lines associated with this production method. The base plate has a slightly raised rim to secure the lid and prevent sliding. Notable features include the Art Deco-influenced geometric silhouette and the subtle light refraction properties of the glass. In terms of condition, there appear to be visible dark spots or residue on the surface of the base plate, which may be surface grime or minor chips; a closer inspection for 'flea bites' along the inner rim is recommended. The piece lacks obvious maker’s marks in the photo, though the style is consistent with manufacturers like Federal Glass or Hocking Glass Company. This item represents a classic example of affordable luxury from a significant historical era, showing hand-finished details in the molded glass.

I have examined the digital images of this pink depression glass butter dish. The piece exhibits the characteristic selenium-based coloration and mold-pressed construction consistent with the late 1920s to early 1930s. The silhouette, featuring a circular lid on a square base, strongly suggests a pattern of the era, likely produced by a high-volume manufacturer such as Federal Glass. Visually, the glass shows appropriate clarity and light refraction for authentic depression-era production. The condition appears fair to good; however, I noted dark spotting on the base which requires physical inspection to determine if it is removable carbon residue or structural 'flea bite' chipping. The market for pink depression glass remains stable among nostalgia collectors, though prices have softened from their peak. Similar covered butter dishes in common patterns currently realize between $40 and $85 at auction. Value is significantly impacted by the integrity of the rim and finial, as these are prone to impact damage. Limitations: This appraisal is based solely on digital imagery. I cannot verify the presence of 'sick glass' (permanent clouding) or microscopic chips along the inner flange without a tactile examination. Full authentication would require a UV light test to check for manganese fluorescence and a physical assessment of the weight and mold seams to differentiate it from 1970s-era reproductions. Provenance detailing the item's history within a single household would further solidify its value.
