On a harshly cleaned coin you would be heavier coin scratches from an abrasive, baking soda, comet, sand paper or a rough pad roughing us the surfaces. The out layer on the coin will be removed during the process. (copper coins might have a pinkish look to them. They scream out cleaned
A set of light coin scratches was probably done with a substance like jewelry cleaner, brasso, tooth paste. these will make the coin look shiny, but you can see swirl lines on the tops of the devices. While the coin may look better, to a collector these are [no no[/b] coins. If you sent one in to be graded, they might give it a 'genuine' coin listing on the plastic, but no grade or they will mention cleaned, altered because the surface was altered to try to trick them to get a better grade. This usually removes about 90% of the value when they are altered. So it is best not to coins surfaces. The future life of that coin is compromised by what you do that coin today, for the rest of it collectable life.
Polishing coins remove the surface and actually remove devices ruining the value for the coin.
