Pennies don't rust; they're copper. They corrode. The phosphoric acid, carbonation and salt in soda will corrode a penny faster than the other liquids.

Will iron rust faster in vinegar or water?
Vinegar. Iron rusting is Fe------> Fe2+ + 2e- . A surface can not just acquire charge so there has to be a balancing reaction to consume the electrons. There are two main ones 2H2O + O2 + 4e- -----> 4OH- neutral and alkaline solutions - relatively slow. 2H+ + 2e- ------> H2 acidic solutions - extremely fast. So whenever acid is present and protons are produced, corrosion occurs faster due to the kinetics of electron consumption.

If you leave the pennies in the mixture too long, holes may start to form in them.
