áThis book is called, Top 100 Morgan Dollar Varieties - The VAM Keys. It was written by Michael Fey and Jeff Oxman in 2009. This book focuses on the top 100 Morgan Dollar VAMs. It is a very informative book that explains everything great. It explains what exactly a VAM is, different ways to collect them, tools that you should have to collect them, and other helpful info. The book gives pictures and information on all of the Top 100 VAMs. The chapter has detailed die markers and tells exactly where to find the VAM. If you are a beginning VAM collector and want to know the ropes then this is a great book. The book is also good for advanced collectors who want a more in depth guide. The book is tiny and sturdy as well. It is a spiral bound book, so you can lay it open when searching for VAMs. Overall, this book is a real help for me and any serious or beginning VAM collector.
