Both shells are the common type APCBC with an explosive charge and a base fuze. The last type you depicted is the older type (8,8cm Pzgr) with the large base fuze (Bdz. fur 8,8cm Pzgr) , the first type you depicted is the 8,8cm Pzgr39 with the Bdz 5127. (small base fuze).
They have both nothing to do with APCR (Armour piercing composition ridgid) which exists of a hardened steel/ tungsten projectile enveloped in a projectile. The other term for APCR is HVAP
They would really fit well in my collection of 8,8cm Flak 18/36 &37 shells.
