A great way to finish a coin matrix routine... after the standard coin assembly, a large "jumbo" half appears under the cards.  Then three more large halves appear.   And then you could just as quickly make them all disappear again.

This set of four chrome coins (three shells and one solid coin) all nest into a "single" coin.  Think of the possibilities.  (You will have to, because this set comes with no instructions...)

For the experienced coin worker, this set is highly recommended to add some surprising BIG finishes to your coin routines.
