Has anyone read and have opinions of the following books by Q. David Bowers. I am particularly interested in US gold coins, and I was wondering if these were worth getting (they are pretty expensive). Also, any other books you recommend? Thanks. 1. Louis E. Eliasberg, Sr., King of Coins 2. A California Gold Rush History featuring the treasure from the S. S. Central America 3. The Harry W. Bass Jr. Museum Sylloge
