The drachms of Pacorus II on which he is wearing a diadem are differentiated by presence or absence of a beard. Where present, the beard is very short. The two groups can be clearly discerned on these example photos:
Group I: No beard
Group II: Light beard
The drachms of Pacorus II (type 73) always have a youthful portrait with no beard.
Note: Beardless portraits are unusual on Parthian issues. The beard is missing only on the earliest coins of Arsaces I, Arsaces II and Mithradates I, and on the coins of Pacorus I (c. 39 B.C.).
The drachms of Pacorus II (type 75) always have a portrait with a short or light beard.
