I was looking for some advice on a good book to teach someone who doesn't really know how to grade (me and without online photo grade) and one easy to understand. Also it's for u.s coins. Thanks for your time.
Buy the ANA book, but do so with the clear understanding that no book can really teach more than the basics. After this, about the best you can do is to spend near countless hours browsing Stack's, Heritage, etc archives to get a better understanding of how different examples are graded. Of course, it is much better if you can attend a show to view coins in person, but if you cannot, use the aforementioned sites along with the book to your benefit. The ability to properly grade comes with time and experience... an overly generalized link with basic descriptions is really of no help. While photograde can be useful, it too can not truly teach anyone to grade.
To me, books are a good way to understand grading, but they really stink in teaching you how to grade. The way I learned to grade was by looking at lots and lots and lots of graded coins. Many online, and even more in-hand at shows. I would recommend you do the same. To answer your question directly, here are a few grading books in my library: ANA grading guide PCGS grading guide Photograde EAC grading guide / booklet All of them are good sources of information, but poor learning vehicles, IMO. BOTTOM LINE: If you want to learn to grade, there is no substitute for looking at lots of graded coins in-hand. Reading books and looking at online photos are a poor substitute, but better than nothing at all.
