Instead of buying the book, I'd recommend you to buy some coins instead from MinerJones or anyone else.
Thats certainly ones own decision to make, and Minerjones if certainly a very trustworthy seller. I wholeheartedly would recommend picking up some coins from him.
If one wants to learn better about the subject and have a catalog of large color photos of every coin made to date, this book will be an excellent reference. It will discuss all kinds of topics related to the subject and should be an excellent place for someone wanting to learn more. The book will be about 270 pages in full color, and a limited first edition of 100 hard copies.
