You will also learn how to identify coin errors, which sometimes are worth more than even the rarest of coins. The information in this book is a must-know for any collector, and can help you "Strike it Rich" with coins that which many can be found in your pocket change. However, there are a few problems with the book. The book isn't in full color which is an annoyance, and the text is not as detailed as I would have preferred it to have been. Overall though it is a decent book, but I would not recommend purchasing it. I give it 3.5 out of 5 stars.
