An older glass Gatorade bottle does have some value because some have sold on eBay as late as 2014. However, do not expect to make very much money.
The value of an old glass Gatorade bottle depends heavily on the condition and the age of the bottle. In 2014, such bottles have sold for around $10.
Gatorade manufactured its sports drink in glass bottles from its first days of production in the 1960s until 1998, when it began using plastic bottles. With nearly 40 years of mass production, glass Gatorade bottles are found often enough, which lowers their value significantly.
