In this Set, the "P" is a "Mint Set" (Uncirculated Coin Set) strike, which are struck at higher pressure on smaller, lower-speed presses.
The "D" is a circulation-finish coin, produced on the main floor's high-speed presses, in the same manner as true "business strike" coins produced for circulation.
Both of these, and the Clad "S" Proof, have the standard low-relief obverses. In 2014, the higher-relief 1964-style obverse was used only in the special sets, and it is quite distinct from the standard obverse. The 2015 circulation-finish JFK's sold in bags and rolls now feature the higher-relief obverse.
