Kurotsuke with COINS - Quarter Version

Effect: You introduce a small, silk bag and five coins; four of these are US quarters and one is a Foreign coin the same size as a quarter. The coins are dumped into the bag and you shake the bag to mix them. You walk up to a member of the audience and ask her to remove one coin, closing her hand around it before the hand exits the bag, so you can't see which coin she took. Just to be safe, you turn your head away during this process. You repeat this process with four more audience members, each taking a coin. After all five coins are removed from the bag, you set the bag aside and then, with absolutely no pumping or outs, and you correctly announce who holds the lone foreign coin. This can be repeated and you will correctly divine who holds the foreign coin each time. Note you receive the special foreign coin, the silk bag and the gimmick. You must supply the 4 US quarters. Bag color may vary. No stooges, no sleight-of-hand (not even a little!) and no verbal artifices!
