Coinmagic by Kaufman is a must !!!
Intermediate and advanced coin Technique by Rubinstein is pretty good and worth buying.
Jimmy Buffalos's book had a good review, but I haven't got it yet.
The Unexpected Visitor is very good, but the plots are reworkings of standard routines. Still buy it !
Neither -
Gary Kurtz's nor Michael Gallo's books are all coins but both have a fair amount and are good books anyway.
You will get flooded with books on coins. There are dozens, but the above are the best I know.
