Now to your question: Personally, I hate the Raven. You will need to wear certain clothing, the reset isn't very quick and you don't need all this just to vanish a coin (and not just any coin at that). You could accomplish basically the same effect with sleight of hand.
Instead of the Raven, get either "Bobo's Modern Coin Magic" or "In the Beginning there were Coins". Both are excellent sources for learning coin magic.
