The value of them is like what....1 Cap? and do they bear any weight? how many do you have lol? They're pretty abundant in NV compared to fallout 3. So yeh useless...unless you collect tons of them and keep selling them for 1 cap a pop. There's easier and less tedious ways of making caps....
True it says they are practically worthless, but in Fallout 3, there was a woman in the BoS that would buy pre-war books for 100 caps each. Not sure if there is someone like this New Vegas.
