| Reverse description | Aniconic reverse displaying multiple horizontal registers of angular Kufic Arabic script filling the central field. The legends include the name and titles of the caliph al-Ma'mun along with pious religious phrases affirming the prophethood of Muhammad. The marginal legend encircles the field in a continuous band separated by a linear border, following the standard Abbasid epigraphic dinar format established under the monetary reform of the early Abbasid period. The strike is bold and typical of the high-quality gold coinage produced under al-Ma'mun's reign. |

| Additional information |
Al-Ma'mun's reign produced some of the most intellectually charged coinage in Islamic history, issued from a caliphate actively funding the translation of Greek scientific texts into Arabic through the Bayt al-Hikma in Baghdad. His dinars are notable for carrying explicit theological statements reflecting his controversial Mu'tazilite sympathies — the doctrine that the Quran was created rather than eternal — a position he attempted to enforce through the Mihna inquisition beginning in 833, the final year of this issue's range.
