Devil's Dimes by Stan Lobenstern

Four loose dimes are shown in the right hand. The dimes are then placed in the left hand. A half dollar is then taken out of the pocket and placed into the hand containing the dimes. The left hand is then opened to reveal a half dollar and a dime. The other three dimes are gone and everything can be examined. Now, that's inflation!

This is a vintage piece no longer in production. Comes complete with illustrated instructions.
