This coaster looks so real that you can even leave it out on the table without the risk of anyone even noticing it or guessing it to be a magic prop.
With this coaster you can visibly vanish a quarter, right in front of the eyes of the audience without any cover or palming.
Borrow a quarter from the audience. Place it on this coaster. Rub the quarter and it instantly vanishes. You can do this completely surrounded and your hands are clean at all times.
The coaster is made of wood and lacquered to a high glossy finish. It measures around 3 3/4" x 3 3/4".
