Yet again Kenneth Bressett and R.S. Yeoman have outdone themselves. While not as detailed as the "Red Book", this book tells you, or gives you an idea, of what a dealer would pay for your coin. VERY valuable if your bidding at auction. You'd be suprised at what coins "trend" for then what a dealer will actually BUY them for. Sometimes about 1/4 of the trend. Great book if you don't want to get "suckered" into a bidding war!
