AI Appraisal Estimate

This is a vintage flower frog, manufactured in pressed uranium glass (also known as Vaseline glass), which exhibits its characteristic lime-green hue due to traces of uranium oxide. The piece likely dates to the Depression era, approximately the 1930s to early 1940s. Centrally, it features a raised cylindrical 'well' design designed to support a figural insert, flanked by two circular holes on a flat, clover-style base for stem placement. The glass is thick and transparent with visible mold lines indicative of mass production during the early 20th century. While it lacks a visible maker's mark in the photograph, the silhouette is consistent with designs by major American manufacturers like Cambridge Glass. The condition appears fair to good; there is notable surface grime and small dark debris caught within the crevices and near the base. A small fracture or impact mark is visible on the inner rim of the central cylinder, and there are minor flea bites and shelf wear along the scalloped edges of the base. If exposed to a long-wave ultraviolet light source, this item would emit a strong neon green fluorescence.

I have examined the digital images and description of this Cambridge Glass #3011 green uranium glass flower frog. This specific 'two-hole' design was produced by the Cambridge Glass Company during the early 1930s. The piece exhibits the correct lime-green coloration and mold-line placement characteristic of Depression-era pressed glass. The fluorescence described confirms the presence of uranium oxide, which is consistently sought after by specialized glass collectors. Upon visual inspection, the item exhibits several condition issues that negatively impact its market value. While the mold strikes are crisp, the presence of a fracture on the inner rim of the central cylinder is a significant structural flaw. Combined with visible shelf wear and minor 'flea bites' along the scalloped base, the piece cannot be graded as Mint. These imperfections are common for utility items of this age but do deter premium-tier collectors. The market for Depression glass remains stable, though common flower frogs often see high volume and moderate prices. Comparables for this specific model in perfect condition typically sell between $85 and $110. Due to the identified damage, this specimen sits in a lower bracket. Limitations: This appraisal is based solely on photographic evidence. A definitive authentication would require a physical inspection to check for modern reproductions (though this specific mold is rarely faked) and to confirm that the 'fracture' is not an internal heat crack. I would also verify the glass density and surface texture to ensure it is period-correct. Provenance documentation or original catalog matching would further solidify its history.
