You will need a basic understanding of sleights to do the routines in the book. I would suggest getting Modern Coin Magic by J.B. Bobo; it is a fantastic book on coin magic.
Stars of Magic is one of my favorite books. I would not suggest buying it ONLY for the coin stuff included in it though. There is an abundance of other great effects that use cards, sugar cubes, matches, handkerchiefs, ect... I would definitely buy it.
So to sum it up, get Modern Coin Magic as in introduction to coin magic. If you already do a lot of card magic, Stars of Magic would be a great investment.
