The recent article of Dr. Pankaj Tandon in Numismatic Digest Vol 38 shows complete comparative study on these coins and very much clears the doubt of Purugupta and Chandragupta III being one and the same person. Now what important clarification he clears is that why Purugupta have used the name Chandra on his coins? One possible justifying reason is that Purugupta wanting to wrap himself in the mantle of his grandfather's glory. Because Chandragupta II also had done the same with his own grandfather name. Given the precedent of one king taking the name of his grandfather, it seems quite possible that Purugupta may have done the same especially if he felt weak in the face of his powerful and heroic half-brother and felt that including his glorious grandfather's name would emphasize his lineage and legitimacy over that of his half-brother and would bring himself more glory.
