Hand To Hand Roll
Description Rolling a coin on a flat surface from hand to hand.
Start Hold a coin edgewise between the table and the right index and middle fingers. The middle finger should be at the 2 o'clock position.
Directions
  1. Quickly roll the coin towards the left, using the middle finger to provide the rolling motion to the coin.
  2. Let the coin roll a fair distance across the table to be caught in the left hand between the index and middle fingers and the table.
  3. Repeat the roll with the left hand to get back to the starting position.
Comments With practice you can get the coin to roll quickly back and forth between the hands.

You need to make sure the coin remains perpendicular to the table at all times. If it gets an angle on it the coin will not roll straight. Keep the middle finger parallel to the ground to help ensure the coin will roll straight.
Variations
 You can roll multiple coins at the same time, or start with a coin in each hand and roll them to opposite hands.
