The Effect: You place 1 coin in each hand, palms up, quickly flip your hands over, palms down, and raise a hand to reveal both coins. A great trick to add to a routine and can be repeated instantly with absolutely no setup.
The Secret: Place one coin on the place right below where your right hand index finger (or left hand, whichever hand you write with) and flip that coin into your left (or right) hand quickly, without the slightest hint to your audience. Quick and no setup at all.
