I'd keep it because it has a few weird things about it, at least until you know more about it. I've never seen a Coke bottle that's both embossed and ACL before. Also why is there no city on the bottom, what glass house is MG, and why does it seem to have a date code of 1959?
Applied coloured label Cokes came out a bit before 1962 if I recall, and I've seen them both ACL and embossed on the larger Cokes and I think a couple smaller ones. Some on one side, are embossed and ACL on the other.
