As the directions state "This coin gimmick is said to have been used by T. Nelson Downs in his close up work."
Affixed to an early Louis Tannen Token coin. The coin is held from the spectators point of view at the fingertips laid upon the palm of the receiving hand. Upon closing the hand and gesturing with the index finger of the hand where the coin was once clipped in the fingertips the steal is accomplished in a rather smooth and effortless way. Opening the receiving hand shows the vanish of the coin. At this point the coin may be produced from behind the knee neatly balanced on the tip of the right middle finger.
An additional ungimmicked Tannen Token included for a variation to the routine.
