Coke will rust a penny the fastest due to its high acidity and sugar content. Ginger ale and Sprite have less acidity and sugar, so they would not rust a penny as quickly as Coke.
Vinegar is known to rust a penny the fastest due to its acidic nature, which accelerates the oxidation process on the coin's surface. Placing a penny in vinegar for a short period of time will result in visible signs of rust forming.

Salt water will rust a penny faster than vinegar because salt water is an electrolyte that enhances the electrical conductivity, accelerating the oxidation process on the surface of the penny.
