There really IS a written History of Coca Cola Prices! I thought Grandpa was just bluffing when he said he was able to buy a Hot Dog and a Coke for a Quarter...but he wasn't! (he WAS bluffing about killing a Kodiak Bear with his bear hands, mind you...)
FoodTimeline.org covers the pricing of Coca Cola and Pepsi HERE.
They also give you some other sources for reading up on the 'Cola Wars'.
While they mention many sources that we have quoted here, they do NOT list the very famous Coke vs. Pepsi lens! The nerve!
Based on advertisements in the Daily Record (a Morristown, NJ newspaper) over the years, Pepsi and Coca Cola prices look like this:
 Pepsi .05/bottle
 Coca Cola, .05/bottle
 Pepsi, .23/six 12 ounce bottles
 Pepsi, .69/six-pack 12 oz cans
 Pepsi Cola, .88/6 12oz cans
 Coke, .99/1 litre bottle
 Pepsi, .89/2 litre bottle
 Coke, 6.98/two 12-packs 12 oz cans
 Coca Cola, 3.99/two "12" packs
 Coca Cola, .59-.99/2 litre bottle
 Coca Cola .99/2 litre bottle
 Coca Cola, 1.09/2 litre bottle
Wild stuff, huh?
I'd like all of you Grandma's and Grandpa's to comment this blog with your earliest memory of the cost of a Coca Cola. Or a Pepsi.
