there are two that are especially helpful and are a must. Howdy Herz and Bill Cohenour provide the most current information with completness and realistic price guides.
I just got Howdy's 2005 "4th Edition" and it has all the new Las Vegas strikes and Reno's most recent additions: Sands (ALL 4) and the Reno/Tahoe Airport series pictured. Howdy has gone to specific pricing - no longer a range - which reflects current auction values. EVERY silver strike issued (excluding some verieties) is pictured. It has some I've never seen in person like the Caesars, Las Vegas $200 and the Delta Saloon, Virginia City - St. Mary's chuch "Viginia City, N. V."
We, as collectors need to support these catalogers who furnish this type of information so that we will have it available to us in the future.
