Summary: Invaluable Reference
Comment: The Bluebook is an invaluable reference when you are selling coins (along with the Redbook when buying) since it tracks what coin dealers pay for coins. You need to keep in mind that in a "hot" market prices change rapidly which can make the Bluebook "dated" fairly quickly. In any case it does provide a baseline indicating what others have received for coins in specific grades over the past several months giving some indication of what you should receive from a coin dealer.
If you are interested in what you can expect to pay for a coin you want to buy then use the Redbook which tracks the amount dealers charge for coins in specific grades.
The difference between the Redbook and Bluebook indicates the monies retained by dealers for the value they add to collector's trades. So, if you are trading collector-to-collector with no dealer involved, the two references can serve as the high and low bar for the negotiation process.

Summary: Useful, but outdated
Comment: While useful and informative and, indeed, a must if you buy coins, this book is quite outdated. Since the price of gold and silver have gone up considerably and change daily, the effect on coins is intense in many cases.
There are several sites online where you can get more up-to-date information. Yet having this handy is a good idea. I like having something near my work area and in my hands so I can quickly look up the information I want. Then I can follow that up by going to one of the Web sites.
