Money Paddle by Porper

One
of the finest paddle effects in existence. you show a black metal
paddle with three rubber bands. Throwing three coins on the table you
take one and slide it under a rubber band. The magic paddle creates a
duplicate coin on the other side of the paddle. You repeat for all
three coins until you have doubled your money. Now you remove all six
coins to show your reward. It's not over - after showing the paddle
empty, a hundred dollar bill appears on the paddle, trapped under the
rubber bands. You remove this, show the paddle then reveal the secret -
it's all done by mirrors. A mirror appears on both sides of the paddle!
