The green bottle looks to be authentic, and one of the earlier lighter-weight NO DEPOSIT NO RETURN type Coke bottles. I see them more in clear than in green, but I am sure it is real.
The weird thing is that the seller gives NO INFORMATION on what the base markings are, no photos of the base, and just writes "CIRCA 1960s" which means nothing if they can't prove when it was made by supplying info on the date code. Surely that bottle should have a date code embossed on it --- somewhere. (I just wrote to the seller, and I will see if he/she answers).
