This book discusses the history of money, from the days of bartering, and different things that have been used as mediums of exchange through time and in different places.  It includes information about the earliest metal coins and paper money and describes the details of US coins and Euros.  Be wary that the information about Euros could become outdated as countries who use the Euro continue to change.  The first and last chapters sandwich the information of the middle chapters amidst a story of a boy bringing his coin collection in for show-and-tell, which seems to fuzz the lines between fiction and non-fiction.
