Drachm - Napki Malka unknown mint

The Hephthalites — the so-called "White Huns" — controlled a vast stretch of Central Asia from Bactria through northwestern India during the fifth and sixth centuries, extracting tribute from the Sasanian Empire and briefly humiliating it militarily in 484 AD when Hephthalite forces killed the Sasanian king Peroz I. Napki Malka coinage belongs to a ruler-series that borrowed heavily from Sasanian silver fabric while asserting a distinct local identity, issued across an unidentified mint somewhere in the Kabul or Gandhara region.

The attribution range of Mitchiner 1507–09 reflects genuine scholarly uncertainty about die groupings within this type. The Hephthalite monetary system collapsed following a joint Sasanian-Göktürk military campaign that destroyed the empire around 560 AD.
