Cory Glass Coffee Filter Rod (not authenticated)

The item depicted is a molded, clear glass rod designed for use as a coffee brewing accessory, specifically matching the appearance of a vintage vacuum pot filter rod. The piece measures approximately several inches in length, featuring a slender, straight shaft on one end, an enlarged bulbous or flared section near the middle with a textured or frosted grip area, and a specialized tip at the opposite end. The glass is transparent with slight variations consistent with mid-century manufacturing processes. Visible molded lettering directly on the surface appears to read 'CORY FILTER ROD' alongside patent or design reference text, which aligns with the owner-supplied unverified notes referencing a Cory filter rod and patent numbers. The physical condition appears generally intact with no major visible fractures or repairs noted in the photo, though minor surface wear and handling marks may be present upon closer physical inspection. This identification rests on the visible molded text on the glass body, while the actual authenticity and specific production date remain unverified. The style is consistent with mid-20th-century kitchenware and coffee accessories, utilizing molded glass to function as a reusable filter component for vacuum-style coffee makers. Quality indicators include clear mold seams and legible raised lettering, typical of mass-produced utilitarian glass items from the mid-century era. User-supplied context notes 'Cory Filter Rod. Pat 1927287', which is treated here as unverified information.

Based on what I can see in the provided image, the item is a molded, clear glass rod bearing raised lettering that appears to read 'CORY FILTER ROD' alongside patent reference text. The user supplies the context that this is a Cory Filter Rod associated with Patent 1927287, and this estimate assumes that user claim is correct. However, I can't verify from a photo whether the piece is a period-correct mid-century utilitarian item, a later reproduction, or a replica, as visible molded marks can be duplicated. Physical inspection would be needed to confirm the glass composition, manufacturing seams, and surface wear consistent with the era. For the purpose of this appraisal, assuming the attribution is correct, similar vintage glass vacuum pot filter accessories typically trade within a modest market range of $25 to $50, driven largely by mid-century kitchenware collectors and vacuum pot enthusiasts. Demand for such utilitarian pieces is generally niche. If the item turns out to be a modern reproduction, replica, or unattributed copy, the value would likely drop to the $10-15 range, functioning merely as a generic prop. To confirm authenticity and exact period of production, an in-person examination by an expert in vintage kitchenware or material analysis would be required, along with potential patent documentation alignment.
