1 Dirham - Ya'lâ b. Ahmad

The Banu Ifran were a Zenata Berber dynasty operating out of the central Maghreb, and their coinage is among the least documented of any medieval Islamic issuer — partly because they navigated between Fatimid and Umayyad pressure simultaneously, minting on their own authority during windows of political independence that rarely lasted long. Ya'lâ b. Ahmad's decade of rule produced very few confirmed numismatic survivors, making each attributable piece genuinely useful for establishing the dynasty's chronology.

A#457M is a sparse reference, and the exact mint for this issue remains unresolved in the literature.
