US Numismatics Discovery Models - Part 1
The following three models explains the different possible types of US numismatic discoveries. The legend for the models:Black Circle - Current Documented Knowledge DomainBlue Triangle - Addition of new knowledge to the Current Documented Knowledge DomainA discovery is made when new knowledge (Blue Triangle) is added to the Current Documented Knowledge Domain (Black Circle). As a result, the Documented Knowledge domain increased with the new discovery. An example of a knowledge domain is the entire documented Lincoln Cent knowledge database (books, catalogs, etc...). The following examples shows the different ways a knowledge domain is expanded.Model A - Previously Undocumented Physical Error Example - The initial discovery of the 1995 DDO Lincoln Cent error. Model A - Previously Undocumented Physical Variety Example - The initial discovery of the 1964 Accented Hair Kennedy half dollar.Model B - Previously Undocumented Physical Issue - The initial discovery of a pattern.Model B - Previously Undocumented Physical Variety - The initial discovery of a pattern produced in silver (only copper specimens are known)Model C - Previously Undocumented Unorganized Grouping - The initial discovery of the Saddle Ridge hoard.Model C - Previously Undocumented Organized Grouping - The initial discovery of President Eisenhower's personal coin collection (yes...he had a personal coin collection).US Numismatics Discovery Models - Part 2 examines how an entire US Mint series was discovered!
