Humran b. Aban served as governor of Kirman under the early Umayyad administration, and this drachm belongs to the transitional Arab-Sasanian series produced before Abd al-Malik's sweeping monetary reform of 696 AD replaced figurative Sasanian-derived coinage with purely epigraphic Islamic types. The four-year window between 692 and that reform is narrow, making dated issues from provincial governors like Humran genuinely scarce relative to the better-documented mint output of major centers.
The light weight against the Sasanian drachm standard reflects ongoing silver debasement in the post-conquest provincial mints.
