Presidential Numismatic Artifacts (aka PNAs) with ties to President John F. Kennedy are limited to a single issue (based on current research).  However, the backstory of how original recipients were awarded the medal is interesting to say the least.

The Jack Medal. The original recipient of this medal was in the US Embassy in Dublin, Ireland when he received this presentation piece. A letter of provenance was initiated with his widow when the purchase was made. The original recipient was employed by the Department of State. His obituary was located and is shown. Items redacted are for privacy.

The Mary Gallagher Medal. Mary was the personal secretary of Mrs. Kennedy. This medal was purchased from her estate.
