Amber Coca-Cola Straight-Sided Bottle

This is a vintage amber-colored glass Coca-Cola bottle, characterized by its 'straight-sided' design which predates the more common contour or 'hobbleskirt' shape. The item is crafted from thick, translucent amber glass and features an embossed script logo. Below the script, additional embossed lettering is visible, including 'REG. U.S. PAT. OFF.' and a series of numbers that likely indicate the glass plant and year of manufacture. The bottle features a crown-top finish which suggests a manufacturing date in the early 20th century, specifically between 1900 and 1916. Its construction shows the hallmarks of early machine-made glass including visible side seams. The condition of the glass appears to be fair to good, with signs of minor surface wear, internal residue, and potential 'case wear' common with circulated bottles of this age. The amber color is a significant feature, as most Coca-Cola bottles from this period were clear or aqua; amber variations were predominantly produced in specific regions like the Southern United States. There are no obvious large chips or cracks visible in the photo, though light scratches and a slight dulling of the glass surface consistent with age (patina) are present. This piece represents a transition period in soda bottling history and displays high-quality historical craftsmanship.

Upon visual examination of this amber straight-sided Coca-Cola bottle, I find it to be an authentic specimen from the pre-contour era, likely dating between 1900 and 1915. The presence of the machine-made side seams and the specific 'REG. U.S. PAT. OFF.' embossing suggests a later straight-sided production. The amber coloration is the primary value driver here; while aqua and clear bottles were standard, amber variants—often associated with bottlers in the South or Midwest—carry a significant premium among Coca-Cola completists. The condition appears to be 'Very Good' (7.0-8.0 on a bottle-specific scale). I note light case wear and surface dulling, which is typical for bottles that were recycled through pressurized washing systems. There are no manifest 'pot stones' or 'sick glass' (permanent mineral etching) visible, though internal residue is present. Market demand for amber 'straights' remains robust, with rare city-state variants from particular bottling plants occasionally exceeding $1,000; however, based on the visible markings, this appears to be a more common regional variant. Limitation: This appraisal is based solely on digital images. Without a physical inspection, I cannot verify the presence of 'flea bites' on the crown finish or micro-cracks (stars/bruises) in the base which would significantly reduce value. A definitive authentication would require a tactile examination of the glass density, a 'ring test' for structural integrity, and verification of the base markings to identify the specific bottling plant. Provenance regarding the bottle’s find-site (e.g., an excavated privy or attic find) would further solidify its historical context.
