American Mid-Century Coca-Cola Porcelain and Metal Gas Station Service Sign
LANGUAGE UNLOCK
Glossary Roundup
Original Presentation Script
Now this is a piece that stops traffic — an American Mid-Century Coca-Cola Porcelain and Metal Gas Station Service Sign. What we’re looking at is a classic roadside enticer: a bold red Coca-Cola button perched above stacked service panels promising gas, lubrication, washing, and rest rooms. It’s the full-service dream in steel and porcelain.
The Coca-Cola disc, with its ‘In Bottles’ slogan and patent marking, places us squarely in the 1940s to early 1950s — the golden age of roadside America. These round porcelain buttons were often mounted high on poles, but here we see it integrated into a curbside service stand — a format that’s highly collectible in petroliana circles.
Materials matter. The top sign appears to be true porcelain enamel on steel — note the gloss, the depth of color, and the small edge chips exposing dark steel beneath. The lower panels are painted steel with raised green lettering, mounted on a tubular steel frame with a circular base — all consistent with mid-century fabrication techniques.
Condition shows honest age: edge chipping, oxidation at seams, and paint loss on the frame. That patina is your friend. It tells a story. I see no glaring red flags of a modern reproduction — but I do flag the possibility this is an assembled piece marrying an original Coke button with period service panels.
A word about copies.. Reproduction Coca-Cola signage is everywhere — especially porcelain buttons. Many are artificially aged. Always inspect for correct weight, porcelain depth, and period hardware.
Authenticity score: 70%. If fully period and original as a unit, I’d place auction value at $3,500 to $6,500. If assembled or partially reproduction, more in the $800 to $1,500 range.

Curator Questions
Curated by Jade
Assessment:
This appears to be a desirable mid-century American gas station curb sign combining a porcelain Coca-Cola button with service advertising panels. The Coca-Cola disc shows surface wear, minor chipping, and honest patina consistent with age. The lower service panels and frame exhibit oxidation and paint loss, but their construction and wear patterns suggest mid-20th-century manufacture rather than a modern reproduction. However, the combination format raises the possibility of an assembled piece using an original Coca-Cola sign with service panels from another source. Close inspection of mounting hardware and manufacturer stamps would be necessary to confirm originality as a complete unit.

Provenance:
No provenance documentation provided.
Condition:
Very Good (honest surface wear, porcelain chips, oxidation to frame, structurally intact)
Identification Score: 95%
The Coca-Cola script, phrasing ('In Bottles'), and service panel typography clearly identify this as a mid-century American gas station service sign.
Authenticity Score: 70%
Surface wear, porcelain aging, rust at seams, and period typography support authenticity, but the assembled nature of the unit (Coca-Cola disc paired with service panels) warrants caution pending inspection of maker marks and original mounting hardware.
