How old is this Coca-Cola bottle?

Question

I was just curious to see how old this Coca-Cola bottle is. Its tinted-green, says Coca-Cola on it on both sides. (It also says "trademark registered" and "in US Patent Office.") The bottle is 6 1/2 oz. Its really heavy, and has a really thick bottom. Its pretty much your standard Coke bottle. I think its before the 50's, but im not sure. Im not looking for anything specific, just the decade.

Answer 1

probably in the 60s

Answer 2

It was from 1920's that it started then later they just made it better...

Answer 3

Hard to tell because every so often they bring those little bottles back.
