What is the value of a World War 2 ration book with one stamp intact?

Well the stamp by it's self is worth no more than a dime so on a book WITH A SPINE INTACT it might be a half dollar also depending one what book it is book one is more rare than book two or three.The condition os a factor obvously the the better condion would sell for more.another thing is the cover does it have one is it still attaced, what about the backing is it still there .Also less of the ration stamps were used in books two & three making them less valuble.i can't tell you mutch but I can tell you that it could be anywhere from thrity cents to a dollar and a half.
