I have an old coka-cola bottle that is the straight sided style. I have researched a bit but can only come up with an approximate dating around 1901 to 1916. Is there any dating marks on these that would give a year? Just above the bottom, there are small letters and numbers that read RG & B CO 258 I. Says Coca-Cola on one side and Canton, Oh on the other, just below the shoulder. I am new here and don't know how to load images from my phone yet Thanks in advance.
