Well, I do see split serifs, but the first thing I would do is find a site with pictures of all of the 1972 Kennedy DDOs and compare it. This is less than dramatic than some, I think.
Looks like SDO-001 in the CONECA Master Listings, http://varietyvista.com/Variety Master Listings/kennedy doubled dies 1971-1994.htm#_1972 Attached is information from James Wiles' , The Kennedy Half Dollar Book, page 248.
