Unfortunately, I am not seeing anything that indicates a doubled die. I am seeing some die deterioration doubling on the letters, but otherwise a normal coin. Keep up the hunt!
What you are seeing is Series Doubling on your 71D (SDO-001), which is found on the ODV-003 (Obverse Die Variety). You can read the description in the CONECA listings: http://www.varietyvista.com/Variety Master Listings/kennedy doubled dies 1971-1994.htm#_1971-D Larry Nienaber
