I'm pulling my hair out in that I no longer own a copy of Bobo but am in hope that you may know the name and reference effect for a specific coin move. . . The move was usually employed for making a ditch. . . the performer flicked the coin into the fold of the opposite arm, which could then lap the coin as you recline back. An earlier variant was to act as if you were picking up the coin and actually flip it back towards you, allowing it to fall off the edge of the table into your lap. If you don't know please pass on the question to someone you may know that has this kind of working knowledge, I need to put a name & credits to it for a book I'm trying to get finished up. Thanks!
