MONEY (Canadian) by Nahuel Olivera - Trick

The magician holds an envelope in his hand and tells his audience that he has a Canadian bill inside and that this will serve as his prediction. He announces that this bill is only one among the five existing possibilities (5, 10, 20, 50, and 100). A spectator freely selects one of these five denominations. The magician opens the envelope for all to see. Incredibly, inside is the exact bill that the spectator freely selected!!!
