AI Appraisal Estimate

This is a set of four square-shaped individual glass salt cellars, commonly referred to as salt dips, housed in their original (likely aftermarket or handwritten) storage box. Each piece is crafted from clear, colorless pressed glass featuring a classic square architectural form with straight walls and a recessed interior well designed to hold fine table salt. The glass exhibits the characteristic clarity and weight associated with mid-century American pressed glass production. Based on the handwritten notation on the box cover which reads 'Grandmother McKee salt dishes,' these are attributed to the McKee Glass Company. Each individual dish measures approximately 1.25 to 1.5 inches square. The style suggests a production period from the early to mid-20th century. Notably, the set appears to be in excellent vintage condition with no visible chips, flea bites, or significant scratching on the glass surfaces. The original box lid shows significant age-related wear, including yellowing/toning of the paperboard, some light staining, and handwritten cursive script in blue or black ink. This provenance through the handwriting adds a personal historical layer to the set, though it suggests the box has served as a long-term storage solution rather than a decorative retail display. The craftsmanship is typical of high-quality mass-produced utilitarian glass of the era, prioritizing durability and clean geometric lines.

Based on my examination of these four square individual salt dips, labeled manusciptively as 'Grandmother McKee salt dishes,' I assess them as authentic early-to-mid 20th-century American pressed glass, likely manufactured by the McKee Glass Company. The attribution to McKee relies heavily on the family provenance written on the box lid, as these simple, utilitarian geometric forms were produced by numerous glass houses (including Heisey and Cambridge) and often lack specific maker's marks on small table accessories. The glass appears to offer excellent clarity and is free of the yellowing sometimes seen in lower-quality mixtures, presenting in excellent vintage condition with no visible chips or 'flea bites' on the rims—critical for value in functional table glass. The market for clear, pressed glass salt dips is currently soft, characterized by abundant supply and a narrow collector base focused mostly on colored or highly intricate patterns. While the 'Yellow rose of capodimonte' note provided seems like a misattribution or irrelevant data point for clear glass, the box itself adds a charming layer of social history, even if it doesn't significantly increase the monetary value. Comparables for simple pressed glass master salts or individual dips generally sell in the $3-$6 per piece range. The set of four helps desirability slightly. To definitively confirm these are McKee rather than a look-alike competitor, I would need to physically measure the precise mold dimensions and check for faint fluorescence under UV light, capable of revealing distinct chemical compositions used by different manufacturers. As is, they serve as a lovely, usable example of American industrial glass history.
