Dr. Darryl A. Gomez
Darryl A. Gomez, PhD, is a retired systems engineer, U.S. Air Force veteran, author, and independent numismatic researcher whose scholarship focuses on presidential and Hawaiiana numismatics. He holds a PhD in Systems Engineering and spent his professional career applying systems analysis and engineering methodologies to complex radar and defense systems.
Dr. Gomez is the founder and developer of the Presidential Numismatic Research Framework (PNRF), a structured methodology for researching, documenting, interpreting, and evaluating U.S. Mint presidential coins, medals, and their associated historical records. The framework integrates documentary evidence, provenance, presidential context, and physical artifact analysis to assess historical significance.
His research reflects the application of systems-engineering principles to numismatic historiography, emphasizing a central PNRF principle: historical significance is not presumed—it is demonstrated through evidence.
Research Impact and Presidential Library Contributions
Dr. Darryl A. Gomez’s independent numismatic research has extended beyond publication to contribute to the discovery, identification, interpretation, and documentation of presidential numismatic artifacts held within the U.S. presidential library system. These contributions demonstrate how focused numismatic inquiry can recover historical information that may not be apparent from an artifact or institutional catalog record alone.
Research-Initiated Archival Discovery Event — Eisenhower Presidential Library
In 2013, Dr. Gomez initiated a formal research inquiry with the Dwight D. Eisenhower Presidential Library, Museum and Boyhood Home after identifying an undocumented 1960 Eisenhower Appreciation Medal variant. The inquiry led to examination of archival material that had not previously been studied from a numismatic research perspective, including records from the papers of Colonel Robert L. Schulz, Military Aide to President Eisenhower.
Analysis of these primary sources revealed manufacturing records, mintage and destruction figures, distribution information, and design attribution to U.S. Mint Chief Engraver Frank Gasparro, providing documentary evidence necessary to reconstruct significant portions of the Eisenhower Appreciation Medal program. Within the PNA Registry research methodology, this sequence is classified as a Research-Initiated Archival Discovery Event (RIADE)—an instance in which an independent research inquiry initiates archival engagement that brings previously unrecognized evidence into the numismatic historical record.
Research-Initiated Institutional Discovery Event — Nixon Presidential Library
Dr. Gomez’s original research into the Eisenhower Presidential Medal of Appreciation—Class 4 reconstructed its design, inscriptions, production history, and distribution context through White House, Bureau of the Mint, and engraving records. That research was subsequently provided to the Richard Nixon Presidential Library and Museum, where a corresponding medal existed in the institutional collection without documentation establishing its purpose or program classification.
The resulting research supplied historical and numismatic context through which the artifact could be identified and interpreted. Within the PNA Registry methodology, this is classified as a Research-Initiated Institutional Identification Event (RIIIE)—an instance in which original independent scholarship enables or materially contributes to the institutional identification of an artifact without implying institutional endorsement of the researcher or methodology.
Eisenhower Library Catalog and Specimen Research
Dr. Gomez’s continuing research has also contributed to the interpretation of Eisenhower Presidential Library numismatic holdings. Catalog identifiers developed through his research have been incorporated into reference information associated with the collection, while subsequent examination has contributed to the identification and reconciliation of individual presidential numismatic artifacts.
This work includes the discovery of the institutional location of nine intact Eisenhower presentation specimens, an important connection between documentary evidence of presidential presentations and the surviving artifacts preserved within the repository.
Research is also underway concerning Eisenhower Library specimens 71-474.3a/b. Dr. Gomez’s examination indicates that these specimens may be attributable as 1971-S Uncirculated silver Eisenhower dollars, based in part upon identification of their Mint marks. Because this attribution remains subject to independent verification, it is presently treated as a pending Research-Initiated Numismatic Attribution rather than a completed research-impact event.
From Research to Historical Record
Together, these research-impact events illustrate a central principle underlying Dr. Gomez’s work: numismatic research does more than describe an artifact. When physical evidence, archival documentation, institutional records, and provenance are systematically correlated, research can discover previously unrecognized evidence, identify previously unexplained artifacts, refine institutional catalog information, and reconstruct historical relationships that have been obscured by time.
This research philosophy ultimately contributed to Dr. Gomez’s development of the Presidential Numismatic Research Framework (PNRF)—a structured methodology for evaluating presidential numismatic artifacts through documentary evidence, provenance, presidential context, and demonstrated historical significance.
