Antique Coca Cola Bottle Very Simple Straight Sided Crown Top

This is a glass bottle that has been in my family a long time. It stands about 8 inches tall. The glass has a green hue especially at the bottom where the glass is very thick. The top is a crown top style and the bottle itself is in the style typical of the straight edged. Right along where the bottle tapers down at the bottom of the neck there is a ring that bevels out from the rest of the bottle like a rim going around. Below that is the inscription COCA-COLA Written in very plain and small non-stylized text. Below this says "CONTENTS 6-FLU.OZS." turnin the bottle around it says "BOTTLING WORKS URBANNA, VA. There is a seam going down along each side of the glass as well. This tapers down to a seam that goes around the bottom of the glass. On the bottom edge is written the numbers "3574" then "ROOT" then "23". Bubbles are inside the glass of the bottle and can be seen here and there along the inside of it. The glass is very thick. I thought it funny that Coca-Cola is written in plain text and right in the same size as the other lettering. Not sure if this is anything special or if it means it is some old knock of f brand. The bottle is very old.
