I have noted that many magicians fear to end not clean. They want coin vanishes where both hands are empty. In a coins across the last coin needs to be overly clean and the hand totally empty.
I do not fear that. I keep my coin palmed. No need to put it in a top it or ditch it in a pocket.
I do not know where this fear comes from, nor do I care. But I realize that this is one of the driving forces of the magic industry. Horrible coin vanishes are published, like the revolution coin vanish, because in the end the hands are empty.
Sometimes it matters, to be able to show your hands empty AFTER a certain trick. But most often it doesn't.
