Chocolate Coin is an effect by Paul Harris and Dick Ryan, based on his Peeler principle, idea that was first published in A Close-up Kinda Guy (1983). It was also included in his compilation Art of Astonishment Volume 3.
The silver surface of a quarter is scrapped back revealing that it is actually a Swiss (chocolate) candy.
