I would also suggest Bobo's, it's where I started. If you prefer to learn from DVD's Metal is a good choice (as DavidTang said) but expensive, you can probably get something like David Roth coin DVD's relatively cheap these days.
My main love is coin magic - it always has been and I guess it always will be.
As already mentioned, Bobo is often referred to as the coin workers bible.
That said, to learn some really powerful coin magic from scratch, I'd unreservedly recommend Harry Lorayne's 'The Magic Book'.
Harry may not have the reputation as a coin worker but it was this book that fuelled my fire in coin magic way back during 1978. Even to this day, I truly believe it contains some of the best written instruction for coin magic that it's ever been my pleasure to study.
