NEITHER.
You should never try to clean collectible coins because anything you have at home will damage the surface and destroy any extra collector's value.
OK, if you just have an ordinary penny from your pocket change, go ahead and clean it but all you'll have is a shiny coin worth 1¢.
If it's an old or valuable penny, please just leave it alone.

Grape juice is not the best choice for cleaning pennies. Lemon juice cleans pennies best due to its acidity.
Because they are full of acid
Lemmon juice is acidic before eating but is alkaline in the body

Its acids
Lemon juice. Vinegar & saltcleans it even better.
Lemon juice. It has a pH of 2.3, whereas orange juice has a pH of 3.3. What is being cleaned off is the CuO and CuCO3 that forms on the penny. Both O2- and CO32- are bases, so the stronger the acid, the more effectively they will be reacted away. I did a quick online search for the pH of grape juice but did not find anything, but given that it lacks the sour taste that orange and lemon juice have (an indicator of acidity), I would have to assume that it is not as acidic as either lemon or orange juice.
lemon juice, because it has antioxidense!>*^#$
