Magician borrows a bill from a spectator. He then takes a simple ball point pen and proceeds to push the point of the pen right through the center of the bill. Spectator actually hears bill being punctured. He then proceeds to rip the pen away from the bill (spectator actually hears bill tearing).
The bill is now slowly and fairly restored and handed back to the spectator. If desired, the pen may be made to penetrate any borrowed coin! There are no sleights required. You can actually write with the pen.
