- Sorry, "Keller Coin Catcher" cannot be purchased.
This effect is very well known with a coin, and in this amazing and popular effect the performer borrows a coin from a spectator. He then proceeds to bite a chunk out of the coin, chew it up a bit, and then spits it out. As the performer spits, the missing chunk of the coin is visibly restored. This effect is very similar in that the performer bites a piece from the key and visibly restores it!
