This is a really commercial coin routine with a wonderful hook. The basic concept is that four coins are going to jump from your hand to the spectators hand. However the reason this works is because of a stranger coin you place into the spectators hand. As a kicker finish the lucky coin is placed away into your pocket. The final coin to travel changes into the lucky coin and all the coins are found in the spectators hand. It's a very commercial plot and with this routine you use no extra coins and no gimmicked coins either.
