EFFECT: The magician places a card box on top of an empty glass. Showing a silver dollar, he vanishes the coin. Holding the invisible coin, the magican appears to throw/drop the coin towards the card box. The coin materializes and drops into the glass with an audible clink. The effect is then repeated for a total of four coins dropping into the glass.
