The magician shows two playing cards, both sides, and his hands completely empty. The two cards are put together face to face and a jumbo half dollar coin appears from in between them. This is repeated three times causing three more jumbo coins to appear from nowhere, always showing the cards both sides and the hands empty. The clear conditions in which this effect takes place makes it a miracle.
This is just one of the many possible effects that can be accomplished with the Misers Half Dollar gimmick. Other classics such as Three Fly and Coins Across are made possible with this gimmick.
