First of all, please stop with the b$ conversation. Some people like it, some don't. Oh well. To each his own.
Personally, I've used the Raven for years and love it. Most magic is not the trick, but the person doing the magic. I tailor the trick for what I want to do. I do not do the shirt method at all, that's not my style. I do the jacket sleeve method, which for me works a lot better and is a lot cleaner.
Second, I never do the trick as a "Look, I'm going to make your quarter disappear in my hand". I'll simply go up to someone, while talking hook it up, and ask to borrow a quarter. I ask them a question like "How long have you had this quarter," in a real serious voice which usually gets a serious response or a laugh. When the respond, bam...the switch. Then I say "watch", put it on the back of the persons had, and do it. Most of the time, the reaction is great, and even better when I look at them, say "that's strange" and walk away without another word.
The other way I do it is do a bunch of tricks for people, get them all hyped up and blown away, then right before I leave as Im putting on my jacket I'll do the above trick.
The trick also works great when you get a "window". What I mean is, you got it with you, you're doing magic, and someone asks if you can do coin stuff, or starts talking about coins in some way, or even just pulls out change. Then, people are coditioned that you didn't set up the effect, but it was just spur of the moment.
Its all about presentation, on any trick you get. Even tricks that do most of the effect for you, a good presentation is what makes people think your from another world.
