Well the ball was signed by the real person, but then traced by an amateur, its not a reall signature. People do this to make a lot of them to be sold in stores. It is most important to never retrace a signature regardless if it is done by an amateur or a Professional. I have been asked this question many times. A baseball with light or faded signatures will be worth more than one that has been traced. The signatures could be worthless. This also holds true for cleaning an autographed baseball. Sharpie is not used for signing baseballs because of the porous properties of the baseball will absorb the ink and it will tend to bleed. The same thing will happen if you try to clean it. The stain might lighten, but will spread to a larger area of the ball. What ever you use to remove the stain will have no problem removing the signatures as well. If any liquid comes in contact with the signatures, your baseball will look like a wet piece of mail. For more information on signed baseballs visit the link I left below.
