          Valuations: 
         
            Estimates which appear in this catalogue are 
            provided as a guide to bidders. The information utilized to determine 
            estimates can  vary from the opinion of the cataloger to valuation 
            catalogues and/or information supplied by consignors. Bidders are strongly 
            advised to determine valuation based upon their own research and inspection 
            of the lot. It is possible that in instances where catalogue valuations are 
            provided, errors can occur and therefore it is recommended that bidders 
            evaluate the lot independently.It can be assumed that in many instances lots 
            will realize considerably higher than estimates and in other cases 
            considerably less than the estimated price indicated.
          
         Start Price (Reserve): 
         
            The dollar amount shown at the end of the main description for each lot 
            is the minimum hammer price the lot will be sold for, unless stated 
            differently at the time of the of selling of the lot. (California operation only).
          
         Catalog Number Conventions: 
         
            1) A dash ("-") in a catalog number range indicates the 
            set is complete within that range, as listed by the appropriate catalog. 
          
         
            2) A single slash ("/") in a catalog number range indicates 
            the set is incomplete within that range, and some stamps are missing.
          
         Stamp Centering and Grades: 
         
            The width of margins and the centering of the design within 
            perforations are graded in strict accordance with the Scott Standard Postage 
            Stamp Catalog standards. The following grades are used in this catalog:
          
         
            
               | Extremely Fine: | 
               
                | Exceptionally large margins and near perfect centering. Used to describe stamps which are
                                            of superior grade for the issue. | 
             
            
               | Very Fine: | 
               
                | Normal size margins for the issue and well-centered with design nearly centered perfectly. | 
             
            
               | Fine: | 
               
                | Imperforate stamps may have smaller than normal margins and perforated stamps will be off-center. 
                                            Issues before 1890 may have the design touched in places. | 
             
            
               | Average: | 
               
                | Attractive appearance, but margins or perforations cut into design. | 
             
          
         Covers: 
         
            Minor nicks, tears and slight reduction from opening are to be
            expected in 19th century covers. Folded letters normally have tears in the 
            reverse and file folds, which will not be mentioned unless they
            affect the stamps or markings. Light cleaning of covers is an accepted form 
            of conservation and is not grounds for return of a lot. The terms "Extremely 
            Fine", etc., are meant to convey the overall appearance of cover, not the 
            condition of an individual stamp.
