I'm doing the "Coin In..." table to table here in Hawaii. Nobody, lay or magician, (under the age of 70) has ever seen it. Or at least, can remember seeing it. It's working well for me, and I've discovered the following:
1. The standard "shaking the folder out of the neck into your fist" approach for removing the folder and switching in the regular coin, works. I like and have tried more clever approaches, where the coin appears to have penetrated the side or bottom on the way out, but the extra effort doesn't seem to be worth it. Now I just shake the coin out into my hand, palm it, and drop the regular half into their hands. They immediately dive for the coin, or the bottle. Nobody looks at me. As far as I'm concerned, that's a successful switch.
2. At some point you're going to have to decide who's going to be holding the bottle at the moment of penetration. (I wonder what the Forum smut-editor will do with that phrase?) If you do, you can do the penetration via Williamson's "Striking vanish", which works well for me. (Do not do this with a large wine bottle) On the other hand, if they hold the bottle, you can use a much bigger bottle and you get a great reaction from the person holding it.
3. Do produce the bottle as per John Carney or Jim Stanfield. It works, and it's a highpoint in the routine. I pull the bottle (a small coke bottle)from behind someone's ear.
4. If you pop the coin into a half-filled beer bottle, you can pass it around without fear that anyone will try to shake the coin out.
To answer your question, I'd suggest you read the following:
"Le Perrier"(?) John Carney's routine from Carneycopia, or Ammar's "Encore III"
Don Alan's routine (using a bottle full of water)in Pretty Sneaky (?) what the heck, buy all of his books.
The 3 or 4 routines in Bobo's.
The 2 or 3 routines/handlings in Roth's Expert Coin Magic (the book)
The Johnny Thompson routine availible only from, I'm afraid, Jeff Busby, unless some fellow fourm member has a copy and a sense of irony.
Kevin James' routine for the full-blown, smack down, twist-off-the-bottom-of-the-bottle-and-then-vanish-the-bottle routine, that works standup and close up.
If you're looking for a stage handling (I know you work a lot of comedy clubs, and this is ideal)find anything you can on it by Billy McComb. I believe he did/does it with any coin, British or American, that the volunteer hands him. Sammy Smith also does it on stage, and I believe the Ammar routines are written from that perspective. Kevin's routine has enough stunning visuals to work in a comedy club environment. Ammar seems to be the only person writing about the psychology of the routine, and selling it from the stage.
Good luck, and drop me a line with what you develop. I've got some other stuff on it (like a signed coin, ordinary bottle handling)you might find interesting.
