thanks for the responses, thats all really helpful stuff. I thought psych subt was a good read and had some genius stuff in it, i was looking at getting hold of 2 and 3 so maybe its time to take the plunge, they seem to be pretty expensive now though.
I havent tried this out yet, I can't quite bring myself to do it

but my plan was to play it as NLP (I dont believe in this at all btw, but people seem to lap it up) and go for a pattern interrupt kind of shtick. So start shaking hands (tightly, so they wont feel the pressure of the coin on their hand, they'll just think its my palm) then guide their hand so it is palm up during the shake, look them in the eye and ask for their other hand and then guide it on top so they now have their hands together and the coin is hidden (and hopefully they havent noticed). Obv you'd have to keep talking to provide some extra distraction aswel. Psych force or equivoque the coin, get them to imagine the coin materialising in their hand and voila.
This would probably only work one on one because I think spectators would see the coin in their hand before the cover. But hopefully they would be interested enough not to give it away most of the time and if the mark names the coin correctly, theres still some magic for the spec to be impressed by.
and if it does all go tits up, i can always resort to the punch in the face and leg it hehe
oh, and thats a really good idea about the 'new coin' thing. Really clever! thanks Philip
