King's bust facing right / Bull reclining right over a wavy line, with slightly abbreviated Brahmi legend around (5 o'clock): Parama-bhagavata Maharajadhiraja sri Skandagupta Kramaditya ("King of Kings Skandagupta Kramaditya, great devotee of Vishnu"). Struck somewhere in NW Maharashtra (Mumbai?) or just north of it. 12mm, 1.84 grams. Todd/Fishman "The Silver Coinage of the Gupta Empire and Associated States" (2024) #G31b; Michael Mitchiner, Ancient & Classical World, 4881. 

Type with the proper royal title of Skandagupta, Maharajadhiraja ("King of Kings" or "Emperor").

This is the rare bull type of Skandagupta, a numismatic innovation started by him late in his reign, that replaced the normal Garuda symbol on reverse with a Nandi bull, a Shaivite symbol. "Bull" type coins were struck to a 1/2 karshapana standard (about 1.65 gram) and are lighter that the "Western" drachms struck to Western Kshatrapa standard of about 2.1 grams.
