A plain wooden paddle is shown. A penny a nickel and a dime are each secured to the paddle with small rubberbands. Magically a duplicate of each coin appears on the other side of the paddle. You repeat for all three coins until you have doubled your money. All size coins are removed. The paddle is then waved over the coins and a dollar bill appears on the paddle, trapped under the rubber bands. You tell the audience it was all done with mirrors. The bill is removed and underneath the bill is a mirror.
A great pocket trick!
