Hi and welcome
The ROOT marking indicates Root Glass Co of Terre Haute Ind which was in operation from 1901 to 1932, according to Bottle Makers and Their Marks by Toulouse.
I am no expert on Coke collectibles but I suspect this one dates to the earlier end of that date range.
Condition is everything for value - chips and wear are going to hurt the value.
I did some quick searching around and this seems to be a scarce one.
