I want to get a good reference book about Early US Silver Dollars. I've found two listed. The United States Early Silver Dollars from 1794 to 1803, 2nd Edition by M. H. Bolender The United States Early Silver Dollars, 1794-1803 by Jules Reiver Is one the preferred reference? I want one that lists the varieties and how to identify them. Or is there a better one than those two? Also there appears to be two different sets of variety identifiers: BB- and B-. I didn't find anything about them.
The one I use is: The Encyclopedia of United States Silver Dollars, 1794-1804 by Q. David Bowers C2013 Published by Stack's Bowers Galleries I purchased mine directly from Stack's Bowers last year and IIRC it was about $75. It was new and had a nice signature plate inside the front cover that Mr. Bowers had signed. I think this is the latest update on the series. BB is the Bowers-Borckardt number and is the latest die variety nomenclature. B is the earlier Bolender number. There is an even earlier Hazeltine number. This book gives you all three for each die variety so you can cross-reference if you see a coin with only one descriptor.
