AI Appraisal Estimate

This item is a vintage Thermos vacuum bottle, specifically identified by the context as 'Thermos no. 87 1/2'. It comprises a main cylindrical body and a detachable cup that also functions as the outer lid. The main body features a black painted exterior with a distinct horizontal red band, bordered by thin gold or brass-colored lines, encircling the center. The top section of the bottle, where the cork stopper is inserted, is made of a threaded silver-colored metal, likely aluminum or nickel-plated brass, showing some tarnishing and minor scuffs. A natural cork stopper, well-worn and slightly darkened with age, is visibly inserted into the top opening. The detachable cup, also made of silver-colored metal, is heavily tarnished and shows significant wear, including scratches and what appears to be a worn-off or obscured logo/marking on its side. The interior of the cup is not visible, but its exterior design suggests it functions as a drinking vessel and a protective cover for the stoppered thermose. The black paint on the main body shows signs of scuffing, scratches, and loss, revealing the underlying material in some areas, particularly along edges and high-contact points. The red band also exhibits some wear and fading. The overall condition suggests considerable use and age. Given the 'Thermos no. 87 1/2' designation and the aesthetic, this item likely dates back to the early to mid-20th century, possibly 1920s-1950s. The construction indicates a durable, utilitarian design typical of vacuum bottles from that era, focused on insulation for beverages. The visible wear adds to its character as a historical artifact.

I've examined the provided images and description of this Vintage Thermos No. 87 1/2 Vacuum Bottle. Authenticity, based on the design cues, the 'Thermos no. 87 1/2' designation, and the apparent age through wear, appears consistent with genuine Thermos products from the early to mid-20th century. The black body with a red band is a classic design for the era (likely 1920s-1950s). The visible wear, including paint loss, tarnishing on the metal components, and the aged cork stopper, all corroborate its vintage nature and suggest considerable use. The condition, while showing character, is a significant factor in valuation. The extensive scuffing and paint loss on the body, coupled with heavy tarnishing and wear on the metal cup, place it in 'good' to 'fair' condition for a vintage item. This wear impacts its display value. Market conditions for vintage Thermos bottles vary widely. While highly rare or pristine examples, especially those with unique graphics or promotional branding, can fetch hundreds of dollars, common utilitarian models like this, even vintage ones, generally have a more modest collector base. Comparables in similar condition typically sell in the $30-$70 range on online auction sites and at antique markets. The 'Thermos No. 87 1/2' model is not considered exceptionally rare, but its age still holds some collector appeal. Demand is steady among collectors of vintage advertising, kitchenware, or camping gear. Factors impacting value: The primary positive is its authentic vintage status and recognizable brand. The main detractor is its heavily used condition. If the original interior glass liner is intact and functional (which can't be assessed from images), it would add some value. If it were in excellent or mint condition, the value would be significantly higher. Limitations: My assessment of authenticity is based solely on visual cues from the image and owner's description. A full authentication would require in-person examination to verify material composition (e.g., precise metal types), internal components, and to check for any hidden repairs or alterations. Provenance documentation (original purchase receipts, family history) would also strengthen the authenticity claim.
