I'm looking for the name of a certain, common coin flourish. It is when the coin passes under and over each knuckle/joint on the hand. It is shown on most coin magic demo videos. Could someone please tell me what the name for this flourish is and where I can learn it (I already have Bobo's book, if its in there, that's great, I just don't know where it is.) Thanks in advance!

I believe you are talking about the Coin Roll. I imagine it can definently be found in Bobo's book.

Thanks so much guys, I really appreciate it.

it's also called the steeplechase. There is an explanation in bobo's book, and there is a very good visual explanation in David Roth's Ultimate Coin Magic Collection vol. 4 dvd.
