To elaborate, it would be a basket of goods comprised only of Coke, measured using the Coka currency.
It's something like ∂Coke/∂Coka, and historically when gold presumed to be a neutral measurement of value, the price of labor and the price of land still varied with respect to each other.
I am reminded of The Economist's "Big Mac Index", comparing currencies' purchasing power to buy a Big Mac in different countries. The index "seeks to make exchange-rate theory a bit more digestible". ;)
