Al Cohen used to sell a plastic version of this wonderful effect c. 1984 and Joe Porper made a quality version.
Effect: Coin and Money Cups. Joe Porper brings back to life a very old classic close up trick, courtesy of Al Cohen. Two cups are placed on the table and can be examined. Three quarters are borrowed (or you can use your own) and are dropped into any one of the cups by the spectator. The quarters then proceed to magically travel from one cup to another.
As a finale, a stack of nickels appears spills out of the cups.
(Use your own coins.)
