AI Appraisal Estimate

This is a vintage hand-blown glass brandy sipper, also commonly referred to as a whiskey or brandy pipette, produced by the Pilgrim Glass Corporation. The item is crafted from a vibrant lime or avocado green transparent glass, typical of the Mid-Century Modern aesthetic of the 1960s and 1970s. The piece features a bulbous, reservoir-like body with a flat, ground rim and a distinctive long, curved vertical stem that doubles as a sipping straw. On the side opposite the stem, there is a small textured glass application, often called a 'berry' or 'prunt,' which serves as both a decorative element and a functional grip. The base is slightly flared to provide stability. Notably, the original silver and black Pilgrim Glass foil label remains affixed to the front of the body, featuring the company's iconic logo. The overall construction displays high-quality hand-blown techniques with organic, flowing lines. The condition appears to be excellent with no visible chips, cracks, or significant surface wear, and the glass retains its high clarity and brilliance. This item represents a classic example of West Virginia art glass from the mid-20th century.

Based on my visual examination of the described Pilgrim Glass brandy sipper, I have assessed the item as a genuine piece of mid-century West Virginia art glass. The presence of the original silver and black foil label is a significant factor, as it provides immediate provenance and preserves the 'new-old-stock' appeal valued by collectors. The avocado green color is quintessential for the 1960s-1970s era, and the hand-blown execution—noted by the ground rim and applied prunt—demonstrates the high craftsmanship of the Ceredo, WV factory. The condition appears excellent with No visible clouding or 'sick glass' often found in vintage barware. The market for Pilgrim Glass remains steady, particularly for functional barware items. Recent auction comparables for labeled sippers typically fall in the $40 to $70 range depending on color rarity; while green is common, the intact label pushes this to the higher end of the spectrum. Demand is driven by Mid-Century Modern enthusiasts and specialized 'Prunt' glass collectors. However, a definitive authentication via digital images has limitations. To provide a professional guarantee, I would require an in-person inspection to verify the absence of micro-fractures at the stem join and to check the base for appropriate shelf wear consistent with age. Scientific testing is not required for this class of glass, but a physical examination of the glass density and tool marks would confirm it is not a contemporary reproduction.
