You display a dime and penny with holes drilled through them. Stringing them on a cord, you invite your spectator to name one of the coins - the dime or penny. Let's say they name the dime.
Closing your fist, you invite the spectator to hold onto the ends of the cord. Then, you casually pluck the dime off the cord - leaving the penny, dime, and cord intact!
There are no sleights required - this trick is very easy to do. Instructions are included, along with all the necessary props.
