All depends on which series I'm searching for information on I have a favorite book for each one. For general information my favorite is the Coin World Almanac 1990 edition.
I’m out of town till Monday. I’ll send you a photo when I get back…. Unless I misunderstood which book was yours…
I think it would be a good idea to do a large print version of the guide to the large print red books. I think.
I will second the ANA Grading Standards but I use it in conjunction with "Coin World's Making the Grade" I feel between the two of them, I can take any unknown series and learn a lot regarding potential wear patterns and how grade degradation occurs but they both have just a slightly different approach to grading and I think you need to consider both views to be a good grader.
Sorry for the bad photo link. I tried to copy from amazon, secondary to my laziness in not wanting to photograph and edit myself. Oh well.
