The performer shows a pack of cards to be quite ordinary and one card is selected by the spectator (and may be signed).  The card is replaced into the pack which is squared and placed face down on the table. Now a coin is shown and vanished! The cards which have been in full view for the whole time, are cut to reveal that the coin has suddenly appeared in the deck!  
The coin is then removed from the deck and the spectator is asked to name the chosen card.  When the card that was underneath the coin is turned over, it is seen to be the chosen card!
Easy to read instructions included.
Instructions for coin vanish not included (any method may be used).
