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 Domain
Blue Triangle - Addition of new knowledge to the Current Documented Knowledge Domain
A 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!

Extremely interesting article. Imaging the number of models to reverse engineer Numismatics since the beginning of time?

Good job. It DID make me chuckle a little, too. At myself, for being part of a hobby with such interesting avenues to wander and concepts to ponder.
