Dating old coke bottles
I believe he has been looking on ebay with no luck. It would be bad form in my opion to ask a value of a bottle when 10 similar ones just sold on ebay. Also dont always expect a quick answer, sometimes people here are busy or they just dont know. Lettering on the body will give clues to the contents and lettering on the base will give clues to the manufacturer. Is the bottle machine made and aqua- or light green in color? For example, glassblowers still make hand-blown bottles today.Both require more specific research to refine the bottle's date beyond observation of technology. Aqua glass typically dates from the late 19th century to the 1920s. Bottles with a purplish or amethyst hue are made from manganese dioxide glass and date circa 1880 to 1920. Also keep in mind that bottles could have been used and refilled multiple times.(Note: In general, local/regional Coke Vitro mark " data-medium-file="https://i1com/ fit=402,346&ssl=1" class="size-thumbnail wp-image-580 jetpack-lazy-image" title="vitro-mark-on-coke-bottle" src="https://i1com/ resize=150,150" alt="Vitro mark on 2008 Commemorative Coke Bottle" width="150" height="150" data-recalc-dims="1" data-lazy-srcset="https://i1com/ zoom=2&resize=150,150&ssl=1 300w" data-lazy-sizes="(max-width: 150px) 100vw, 150px" data-lazy-src="https://i1com/Contrary to popular belief a Coca-Cola bottle, even if it is decades old, is only worth a few dollars at most.Bottles from larger cities are usually easiest to find, and, in general, the smaller the city, the scarcer the bottles.A common misconception is that the city name indicates where the bottle was actually made.
This includes makers of Coke bottles covering a very wide time period, including the earlier “straight-sides” and the later “hobbleskirt” classic shaped bottle.
A pontil rod held the nearly molten bottle during the final stages of manufacture.
The scar was left when the pontil was detached from the bottle. If the seams disappear in the neck, the bottle was probably "blown-in-mold" and dates circa 1820 to early 1900s.
The Coke Cola bottler in Pensacola, Florida didn't switch and was forced to sell out in 1924. There were alot of error bottles in these two orders. The ferry stopped running in 1938, so it all makes sense. From reading here, it seems asking how mch a bottle may be worth, is considered poor form. One thing I really like about this forum is many have their own specialties and have done volumes of research on those specialties.
The switch actually happened in 1924 to the 1915 bottle. My friend that has a Coca-Cola bottle manufactured before the advent of the hobble skirt design, is trying to figure out it's worth. People ask values in this forum all the time, myself included. I think people do expect you to do a little of your own research first and check the easy sources like Ebay. If I can't find an answer after several searches on the internet, someone here usually can point me in the right direction.
