Worth??

JanO

How do I find out what a old Seltzer bottle is worth? The seltzer top has Warwick Bev. Co. 61 engraved on it. The bottle is clear with design and Rock Creek , sparkling carbonated water, and Rock Creek Gingerale co., Washington D.C., contents 26 fl. oz. The bottom of the bottle has 346. Can anyone help me out?
