The simple, straightforward text is presented in both English and Spanish.  It gives some basic information about money (how much cents makes a dollar, the names of the coins, etc.) and considers different ways coins can be sorted.  My problem with the book is that the only two ways to sort coins that actually serve a real-world purpose are to sort by type of coin and by value, which is really the same thing, but this book dedicates two separate pages to these ways, and also sorts by size, color, and whether or not there are ridges on the edges.  I guess this is fine as a study of sorting, but serves little purpose to understanding money, other than guiding introductory observations.
