*John F. Kennedy $1/2 coins began in 1964.In 1961,it was the Benjamin Franklin $1/2 coin that was being struck.*
Yup. I guess all JFKs were minted after '61.

Even so that '70-D has a lower mintage than any Franklin between '61 and '63. Only when you go back to the proofs of '61 do you get a lower mintage (or some of the more recent silver JFK proofs).
*It was a question requiring some extra thought.*
Yup, I needed some extra thought on phrasing the question in the first place.
