The vinegar and salt in the ketchup will remove most of the dark tarnish on a darkened or dirty copper penny (you can accomplish the same effect more quickly using just a small dish of vinegar and salt). However, the penny will "clean up" with a slightly beige-pink or rosy color, significantly not quite the color of a shiny new penny.
