I defined a new type of historic numismatic specimens as the Unsung First Day Issues and are not readily known by the numismatic nor collector communities. My quick research (less than a week) was instigated by NGC's recent grading of a bag of 1964-D Kennedy half dollars. I agree with their assignment of a "First Day Issue" (FDI) designation. But now it leaves the door open for the Unsung First Day Issues.
What are the Unsung First Day Issues?
These are historic numismatic specimens with the proper documentation indicating it's a true first day of issue from a U.S. Government official (with a direct connection to the U.S. Mint) and gifted to another U.S. Government official.
Item 1. Image of the July 29, 1971 documentation of the FDI 1971 Proof Eisenhower dollar from the Director of the Mint (Mary Brooks) to the Special Assistant to the President Eisenhower (General Robert L. Schulz).
Item 2. Image of the August 6, 1971 documentation of the FDI 1971-S uncirculated Eisenhower dollar (blue pack) from President of the United States (Richard M. Nixon) to a Congressman (Honorable Paul G. Rogers).
Item 3. Image of the November 3, 1965 documentation of the FDI 1965 uncirculated clad Washington quarter dollar from the President of the United States (Lyndon B. Johnson) to a Congressman (Honorable Seymour Halpern).
Item 4. Image of the March 24, 1964 documentation of the FDI 1964-P uncirculated Kennedy half dollar from the President of the United States (Lyndon B. Johnson) to a Congressman (Honorable Robert G. Stephans, Jr.)
All are historic numismatic specimens and are part of the now known Unsung First Day Issues.
Does anyone else have an additional Unsung First Day Issues to share?
