That's what's known as a flavour bottle, which is a bottle used by a local Coca Cola franchise to bottle other local flavours of soda that they produced. I don't see green ones that often, it may have been only produced for one franchisee but without a name on it it would be hard to know for sure which one.
What about the Coca Cola Soda Water bottles that have somewhat of a square lower section with six stars around the top, the company name plus soda water embossed below them and a city & state on the bottom? Any rarity and real value to them? Many thanks.
Some of those have some local interest if they are hard to find examples...plus they are fairly neat looking bottles. I typically see them in the $5-$10 range but some locals might be higher if very rare. Once again, not "real" Coca-Cola bottles so mostly just local interest.
