...but only a penny more!
The metal is probably worth more than the paper. But in terms of legal tender, they do indeed both have the same purchasing power.
Neither is. Density only depends on the substance, not on how much of it there is.

Yes, the pH level of a drink can affect pennies. Drinks with low pH levels (acidic) can cause pennies to corrode more quickly by reacting with the metal, while drinks with higher pH levels (basic) may not have as significant of an effect on pennies.
