AI Appraisal Estimate

This is a vintage mid-century Coca-Cola advertising thermometer, featuring the iconic 'Sprite Boy' character introduced in the 1940s. The piece is circular in shape, likely measuring approximately 12 inches in diameter, and is constructed from lithographed metal with a convex glass or clear plastic lens protecting the face. The background is finished in classic Coca-Cola red with white branding including the 'Drink Coca-Cola' script and the slogan 'Delicious and Refreshing.' The 'Sprite Boy' is depicted in the lower right quadrant, wearing his trademark bottle-cap hat. The Fahrenheit scale ranges from -40 to 120 degrees, marked with white numerals and a diamond-shaped border. At the bottom, manufacturing text is visible, indicating it was 'MADE IN U.S.A.' by 'THE OHIO THERMOMETER CORPORATION OF AMERICA.' The condition shows significant signs of age and exposure; the metal surface displays noticeable spotting and finish loss across the red field. The mounting bracket at the bottom exhibits heavy surface rust and oxidation. The indicator needle is white and appears intact, though the overall patina suggests an authentic vintage item from the late 1940s to early 1950s.

I have examined the digital images of this vintage Coca-Cola 'Sprite Boy' round metal thermometer, manufactured by the Ohio Thermometer Co. The 'Sprite Boy' character, introduced in 1942, makes this a desirable piece for soda advertising collectors. Based on my visual inspection, the lithography, font styles, and manufacturer markings are consistent with mid-century production. However, the condition is a primary factor here; the significant spotting on the red field and the heavy oxidation on the mounting bracket indicate it was likely subjected to moisture or outdoor placement. While the lens appears clear, the degradation of the finish and the rust on the hardware categorize this in 'fair' to 'good' condition rather than 'near mint.' In the current market, pristine examples of this 12-inch model can exceed $400, but the visible surface damage on this specific item necessitates a lower valuation range. The demand for Coca-Cola breweriana remains stable, yet collectors increasingly prize 'uncleaned' original surfaces that show less severe pitting. Limitations: From photographs alone, I cannot verify the mechanical functionality of the thermometer coil or detect professional color touch-ups. A full authentication would require an in-person physical examination to test the metal's weight, check for any modern chemical odors from recent restoration, and use UV light to confirm the age of the paint. Provenance from the original owner or shop location would further solidify the value. Regardless, the historical charm and iconic imagery maintain its status as a collectible entry-level investment.
