What pen to use to autograph jersey number?
 

I am hoping to get a chance to get Dale Murphy to sign a Braves jersey tomorrow night at an event. I would like to have him sign the number on the back of the jersey. It is sewn on and dark blue so I was thinking silver would look good (the jersey is the old powder light blue with dark blue numbers and lettering). Do silver sharpies work well or should I go with a paint pen? Thoughts?
