Provenance: Three Degrees of Separation from President Kennedy

Exonumia | DrDarryl

Most collectors believe collecting U.S. Mint medals is dull and rather boring . . .What if . . .. . . a U.S. Mint medal was struck specifically for use by the President of the United States.. . . the original U.S. Mint medal mintage was a mere 300 specimens. . . . the design on the U.S. Mint medal identifies the President of the United States as the owner and awarder of the medal.. . . you locate such a medal.. . . the medal you located and purchased establishes you with three degrees of separation from the President of the United States.. . . the President of the United States is John F. Kennedy.I made this purchased a few months ago and I made sure that the granddaughter provided me with the proper documentation that established an unbroken chain of legal ownership. See the image.This is one of many reasons why I research and collect POTUS sGm . . . Provenance starts with the U.S. Mint, then the President, then the original recipient, then a heir of the original recipient, then the persistent collector (me). As the third legal owner of this medal, the medal itself is three degrees separated from President Kennedy.Those not familiar with the term "six degrees of separation" ... google it and look for the Wikipedia definition.

Hawaii the 49th State

Exonumia | DrDarryl

One of my passions is Hawaii statehood medals,which includes the Hawaii the 49th state medals!The Territory of Hawaii was vying to be the 49th state to join the United States of America. As you well know Alaska became the 49th state and soon afterwards Hawaii became the 50th state.There was a period of time where many individuals and organizations believed Hawaii was to be the 49th State.Today, there are numismatic reminders of this period: So-Called Dollars HK-722 (nickel-silver), HK-722a (bright bronze), and HK-722b (antique bronze) varieties. These So-Called Dollars is available in two forms (if you can find them): Original and Holed. I believed holed specimens were created after President Dwight D. Eisenhower signed the Alaska Statehood Act on July 7, 1958 allowing Alaska to become the 49th state on January 3. 1959. The holed specimens were in reaction to this event and was one method to physically obliviate Hawaii's 49th state bid from the medal (the other was to destroy the medal in its entirety). But why waste a medal? Just drill a hole to remove the 49th...This is were an issue arises. As you should be aware NGC implements Details Grading for holed specimens. As a result, the NGC population for the HK-722 varieties are ridiculously low for original (unholed) specimens. The NGC population are:HK-722 population is 1.HK-722a population is 4.HK-722b population is 0.Original unholed specimens are a rarity. So much so that in the Hibler Kappen book, So-Called Dollars: An Illustrated Standard Catalog, its HK-722 plate "con" is a holed specimen.In my included images, you will see an image with 5 specimens in my collection:HK-722 - Two holed nickel-silver specimensHK-722a - Two original bright bronze specimensHK-722b - One original antique bronze specimenUnfortunately, my original HK-722b received a NGC Details grade due to surface damage from bronze disease.Another interesting image is the original printing of the Hawaii 49th State brochure in my Hawaii statehood collection. I've only seen one other copy and it was in the National Archives. (link to the copy)

US Numismatics Discovery Models - Part 2

Coins-United States | DrDarryl

The following three models (Model D, E, and F) explains how an entire US Mint® series can be discovered!The legend for the below models:Black Circle - Current Documented Knowledge DomainBlue Triangle - Addition of new knowledge to the Current Documented Knowledge DomainBlue Text - Addition of new knowledge based on the relatively unstudied/undocumented function of the Bureau of the Mint (1984 name change to US Mint®) to produce special medals for US Government agencies (My assigned term of this US Mint® product is special Government medal).Blue Circle - Creation of a new Documented Knowledge DomainWhy are the majority of special Government medal issues kept secret by the US Mint® ? special Government medals are a joint inter-agency effort between an acquiring US Government agency and the US Mint®. The US Mint® enforces confidentiality of this joint inter-agency effort and does not released comprehensive production information related to thesemedals. A good case example is the President of the United States special Government medal (POTUS sGm) series:http://www.potus-sgm.com/In the case of the POTUS sGm series, from 1958 to the present, the US Mint® has never released comprehensive production and general numismatic information related these special Government medals. It took a numismatic researcher to uncover this US Mint series. One injustice from the withholding this information was the fact that these numismatic medals are true to life presidential artifacts that is unknown by historians, numismatists, and collectors.Model D - Previously Undocumented Issue - The initial discovery of a POTUS sGm and its supporting documentation as an official US Mint issue.Model E - Previously Undocumented US Mint Series - The initial discovery of the 15 types of POTUS sGm and its supporting documentation as an official US Mint issue.Model F - Previously Undocumented Knowledge Domain - Filling the knowledge void for the newly documented POTUS sGm Series Knowledge Domain. This is how a US Mint series was discovered!

US Numismatics Discovery Models - Part 1

Coins-United States | DrDarryl

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!
