This was the first show we not only showed our large selection of error coins but were proud to see the debut of a book we co-authored - 100 Greatest US Error Coins.  This is not just some book with cool pictures of really rare Major Mint Error coins.  This book is an educational resource about the circumstances surrounding how each error occurs and the entire minting process.  Complete descriptions and definitions help the reader understand how and why these coins were struck.  This is a must read book published by Whitman Publishing.  Buy this book here or purchase through the Whitman website.  You can't go wrong.  Keep watching for more news about error coins.  In the mean time, Collect, Invest and Have Fun!!!
