Vintage-style green glass beverage bottle base

This item is the base of a molded green glass bottle, consistent with mid-to-late 20th-century soda bottle manufacturing. The glass is a vibrant translucent green, often referred to as 'Georgia Green' or 'Emerald Green' in beverage bottle collecting. The underside features embossed text around the perimeter. Visible markings include 'COCA-COLA LTD.' followed by a stylized 'C' in a circle (indicating a trademark or copyright), the French phrase 'NE PAS RÉUTILISER' (meaning 'do not reuse'), and numerical markings consistent with a mold or plant identifier, specifically the number '12'. There is also a small triangular mark located centrally. The base circumference features a decorative or functional stipple pattern consisting of small, raised dots which helped with grip on conveyor belts and reduced surface friction. The overall appearance is consistent with disposable, non-returnable glass bottles from the Canadian market, given the bilingual-relevant French text. Condition appears fair with some minor surface scuffing and internal residue, though no major chips are visible in the photo. All attributions regarding brand and age are based on these unverified embossed markings which remain subject to in-person verification for authenticity.

Based on my visual analysis of the provided image, this item is a green glass bottle base bearing markings that suggest it was manufactured for the Canadian Coca-Cola market. Per the user's description, the embossed text includes 'COCA-COLA LTD.' and 'NE PAS RÉUTILISER,' which are consistent with non-returnable beverage containers produced during the mid-to-late 20th century. While the 'Georgia Green' color and stippled base are characteristic of mass-produced soda bottles from this era, I cannot verify the age or production origin from a photograph alone. These markings are treated as a working hypothesis and would require a physical inspection to confirm glass density and mold characteristics. The estimated value of $5.00 to $15.00 is based on the assumption that the bottle is a standard mass-produced specimen in fair condition with the noted scuffing. Market demand for individual bottle fragments or common non-returnable bases is generally low, as collectors typically prioritize intact examples with complete labels or unique historical significance. If this item were determined to be a contemporary reproduction or a more modern commemorative piece rather than a vintage discard, the value would likely be negligible. To confirm the authenticity of its age and manufacturer, one would need to cross-reference the plant identifier '12' and the triangular mark with historical glass company records and perform an in-person examination of the wear patterns. Given the high volume of production for this type of glassware, provenance documentation is rarely available, but physical verification of the glass chemistry or mold seams would be necessary to establish a more precise dating.
