I prefer to avoid it myself.
Coke did indeed have special Olympic 8 oz bottles for the Olympics. I have a six-pack in the pantry.

Do not drink them. As has been pointed out above, after nearly 25 years they’ll be flat. Even if they were not, they wouldn’t last much like Coke. During the New Coke debacle decades ago there were people rushing out and buying up a year’s supply of the old formula before supplies ran out. I was laughing at them because the life span of canned Coca Cola is about six months; bottles may be even less.
You get a sort of sharpness in the taste and not much of the cola/brown spice flavor a Coke-head craves.
