The latest version comes in two volumes. The first covers half cents through nickels, the second half dimes through dollars. Choose the volume that covers your needs. Unlike some books like this, I recommend always getting the latest editions of these.
Chris pretty much covered it. Because when it comes to U.S. coins, I am into large cents and Lincoln cents, I purchased volume I. However, I plan on purchasing volume II one of these days just for informational purposes.
