In simple text, supported by color photos, this book does an adequate job of describing different kinds of currency, including cash, checks, and credit cards.  It points out the historical use of shells and stones and beads and beans to serve the same purpose. It explains that most countries have their own kinds of currency, and goes into details describing the different bills and coins of American currency.  It ends with a final “chapter” about using money wisely, discussing the differences between needs and wants, and encouraging the wisdom of avoiding debt.  It’s fine for what it is, but given that it’s intended for early readers, the simplicity of the text limits the depth of the information.
