1 Dirham - Ámir b. Dá'úd Aden

The Tahirid sultans of Yemen were extinguished almost exactly at the moment this coin was struck — the Ottomans under Hadım Suleiman Pasha took Aden in 1538, ending Tahirid rule and incorporating Yemen into the Ottoman provincial system. A dirham issued in Aden under Ámir b. Dá'úd in that same year sits at the precise edge of a dynasty's collapse, likely among the final issues before the mint passed to new authority.
