I stumbled across an old Coke bottle in the woods in an old dump site and I am looking to confirm the age of it and if it is a common bottle. The bottle is aqua green & embossed. One side says Coca Cola, TRADE MARK REGISTERED BOTTLE PAT. D-105529. On the skirt of this side it has a 23 circled c 38. The second side says Coca Cola, TRADE MARK REGISTERED, MIN. CONTENTS 6-FL. OZS.. The bottom of the bottle says PIQUA OHIO.
