If you are trying to make your coins "more collectable", don't do it.
Cleaning coins with any chemicals you have at home will damage the surface and destroy whatever collector's value they may have. You'll be left with a lot of bright, shiny coins that are worth only 1¢ each.
Lemon juice contains citric acid which can help remove tarnish from pennies, while bleach can corrode the metal. However, a vinegar and salt solution is often more effective for cleaning pennies as the combination of acid and salt acts as a gentle abrasive.
A mixture of vinegar and salt can effectively clean copper pennies. The acid in vinegar helps to dissolve the tarnish on the pennies, while the salt acts as a mild abrasive to help scrub away dirt and grime. Dip the pennies in the vinegar and salt solution, then rinse with water and dry thoroughly.
No, lemon juice does not conduct electricity better than vinegar in water. Both lemon juice and vinegar contain weak acids that dissociate ions in water, allowing them to conduct electricity to a similar extent. The conductivity depends more on the concentration of ions present in the solution rather than the specific acid used.
A mixture of vinegar and salt or a paste made of lemon juice and baking soda are both effective at cleaning pennies. These acids and abrasives can help to remove the oxidation and dirt from the surface of pennies, leaving them shiny and clean.

orange works better because it has more citric acids than apple juice does, all the apple juice will do is make the penny stickier.
