This is a three-piece cobbler-style cocktail shaker, characterized by its integrated strainer and cap. The item is constructed from stainless steel with a high-polish, reflective finish. It stands approximately 8 to 10 inches tall and features a classic tapered body that fits comfortably in the hand. The top portion consists of a metal shoulder with a built-in strainer and a small metal cap that features distinctive horizontal ribbed banding for grip and decoration. The middle shoulder section is etched with barely visible text that appears to read 'GREY GOOSE VODKA', suggesting it was part of a promotional gift set or professional barware line. The condition of the piece shows clear signs of use, including significant tarnish and oxidized rust spots on the shoulder area, light surface scratching throughout the polished body, and fingerprint smudges. There are no visible deep dents, but the age patina indicates it dates to the late 20th or early 21st century. The construction is robust, utilizing a simple friction-fit mechanism for the cap and shoulder. It represents a standard piece of commercial grade barware designed for durability rather than luxury craftsmanship, making it a functional collectible for enthusiasts of brand-name spirits.

Based on my visual examination of this three-piece cobbler cocktail shaker, I identify it as a promotional barware item produced for Grey Goose Vodka, likely dating to the early 2000s or late 1990s. The piece is constructed from stainless steel, a standard material for commercial-grade bar tools. The presence of the etched 'GREY GOOSE VODKA' branding on the shoulder confirms its origin as a branded collectible rather than a piece of fine silversmithing. Condition is the primary limiting factor for this appraisal. The item exhibits significant oxidation and rust spotting on the shoulder area, along with generalized surface scratching and tarnish consistent with heavy use and perhaps improper storage. While the structural integrity appears intact—no major dents are visible—the cosmetic damage detracts significantly from its display value. Market comparables for branded liquor promotional items are generally modest. Grey Goose shakers are relatively common in the secondary market, often appearing in thrift stores or online auctions as part of gift sets. Pristine examples might fetch $30-$40 from a dedicated collector of spirits memorabilia, but the visible corrosion here places this firmly in the lower tier of value. Demand is low, as these were mass-produced for marketing purposes. Authentic verification is straightforward as the branding is etched, but without physical inspection, I cannot confirm the quality of the stainless steel alloy or test the friction fit of the cap, which often loosens over time. To fully authenticate the manufacturing period, I would need to check for any maker's marks on the underside base, which are not visible in the provided images.
