Numismatigic

This is one of those mysteries, in which the astute performer will see at once the possibilities for a veritable miracle. It almost can be made into a challenge effect and has practically no explanation.

Five coins are shown and examined. Four of them are United States nickels and the fifth is a Canadian nickel or five cent piece. They are sealed in borrowed envelopes which the performer never has seen or touched. After mixing, they are handed to the performer, one at a time, behind his back. He correctly divines the location of the Canadian nickel among the rest while the sharpest eyes can be watching the procedure.
