embossed coca cola bottles

[j]

what do the numbers indicate on the 6 oz coca cola bottles about in the middle
21-47 or other numbers

One number stands for the bottle mold number the bottle was made in, the other number is the year the bottle was made. I know at one time that Coca-Cola flipped the numbers, it used to be year first, then the mold number. Then at some time around the 1930's (?) they changed it to mold number than year. What does the bottle say under the Coca-Cola script? That also helps determine the year. I'll bet your bottle is a 1947 bottle.

if those are the actual numbers on the side of your bottle it is a 1947.cant be a 21 if it was the 21 would be down on the heel of the bottle. does it have the number pat'd d-105529 below the coca cola one one side. these bottles were made between 1938 and 1951. hope this helps you later greg
