You vertically balance one coin on top of another! Then, while holding the bottom of one coin, your other hand rotates the top coin 90 degrees so that it is now resting sideways opposed to the bottom coin. Still the coin remains balanced! This trick can be repeated immediately with no setup. Great for close-up and walkaround. A perfect impromptu effect. Very easy to perform. The supplied two coins are precision machined. The gimmick is self-contained within the coins (which cannot be examined). Comes with specially gimmicked coins, full instructions for use, and a routine.
