This is a decorative brass or bronze-toned souvenir thermometer shaped like an oversized skeleton key, likely dating from the mid-to-late 20th century. The item measures approximately 6-8 inches in length, based on its scale in the hand. The main body of the 'key' is constructed from a metal alloy with a bronzed or coppery finish, exhibiting a rich, warm patina that suggests age but also careful maintenance. The top bow of the key is elaborately designed with openwork scrolling motifs, typical of Victorian or early 20th-century decorative keys, giving it an antique aesthetic. Centered within the bow is a circular medallion embossed with a cityscape featuring prominent buildings, along with the word 'ATLANTA' clearly visible above the skyline and a smaller inscription, possibly 'GEORGIA' or 'GA', below it. This specific imagery identifies the item as a souvenir from Atlanta. The shank of the key houses a glass liquid-filled thermometer, displaying both Fahrenheit (right side, 0 to 120 degrees F) and Celsius (left side, -20 to 50 degrees C) scales. The background of the thermometer is a light, perhaps aged, yellow or cream color, with clear black numerical markings and a red alcohol column, which is currently indicating a temperature around 70-75 degrees Fahrenheit. The bit of the key is a complex, decorative cutout pattern, including scrollwork and what appears to be a stylized cross or 'plus' sign at its center, surrounded by further arabesque designs. The overall condition appears to be excellent; the metal components show no significant damage, scratches, or corrosion, only a consistent, attractive patina. The glass of the thermometer is intact, and the mercury (or alcohol) column is functional and legible. The craftsmanship appears to be of good quality for a souvenir item, with clear casting and detailed ornamentation, indicating a well-preserved novelty item.

Upon visual examination, this Atlanta souvenir key thermometer presents as a well-preserved novelty item, likely dating from the mid-20th century (c. 1950s-1970s). The item is constructed from a cast base metal with a bronze or brass-toned finish, exhibiting an attractive and consistent patina that suggests age without significant damage. The openwork scroll design and the embossed Atlanta cityscape are crisp and detailed for a souvenir of this type. The glass thermometer is intact, and the alcohol column appears functional and legible, adding to its appeal as a decorative piece. Its condition is excellent for its age and class.
From a market perspective, these types of souvenir thermometers were mass-produced and are relatively common in the collectibles market. Comparable sales for similar mid-century souvenir key thermometers from various cities typically fall within the $15 to $30 range. The value is driven primarily by nostalgia, condition, and specific location appeal rather than intrinsic material value or rarity. The Atlanta connection provides a specific regional demand, but it is not a rare or highly sought-after collectible on a broader scale.
A significant factor impacting value is its status as a mass-produced novelty item, which limits its ceiling. While its condition is a major positive, its inherent commonality prevents a higher valuation. My appraisal is based on the visual information provided. A definitive assessment of the metal alloy would require in-person examination and possibly X-ray fluorescence (XRF) testing, though this would not significantly alter the value for a souvenir of this nature. Authentication of its age is based on stylistic cues, as maker's marks or provenance documents are typically absent for such items.
