I prefer just keeping them in Ziplocs at the parks, then in a bowl at home. My DD would rather be able to play with them, sort them, show her friends, etc than to have them kept in a book. To each their own, but the books are, imho, expensive ways to keep pennies that we'd rather have out. If they held more, I might get one just for keeping them at the parks, but we can fill one of those books in less than an hour even if we're pressing when we run across a machine, not hunting them out....... If you really like them, some of the WDW-design books look really nice, though.
