Codd-Neck Soda Bottle Value Guide

Invented by Hiram Codd in 1872, this iconic aqua-green glass bottle revolutionized the beverage industry by using internal carbonation pressure to seal a marble against a rubber gasket. These bottles are highly sought after by collectors today because many were smashed by children to retrieve the glass marbles, making intact examples a nostalgic piece of Victorian engineering.

What affects the value of Codd-Neck Soda Bottle?

• Condition of the internal rubber gasket, though often perished, can influence the value of pristine specimens.
• Rarity of the embossed branding, with specific local mineral water companies commanding higher prices than generic versions.
• The presence of the original marble, as many bottles were broken historically to access the 'toy' inside.
• Glass clarity and the absence of 'sick glass' or heavy mineral staining from being buried in bottle dumps.

How to Identify Codd-Neck Soda Bottle?

• Look for the distinctive 'pinch' in the neck designed to trap the glass marble while pouring.
• Check for the presence of the original glass marble still contained within the bottle chamber.
• Examine the glass for a thick, heavy construction and the characteristic aqua-green tint common in late 19th-century UK production.
• Identify embossed maker's marks or regional bottling company names molded directly into the glass surface.

History of Codd-Neck Soda Bottle

The Codd-neck bottle was invented by Hiram Codd in 1872 to seal carbonated drinks using a glass marble pushed against a rubber gasket by carbonation pressure. Popular worldwide for mineral waters and soft drinks from the late 19th to mid 20th centuries, Codd bottles became collectible antiques after metal crown caps and improved bottling made them obsolete. Variations were produced in many countries and sometimes molded with maker’s marks or decorative shapes.
