Islamic Coins booklet (Doha)

Islamic Coins is a thirty-page illustrated booklet in Arabic and English, prepared by the Department of Museums and Antiquities of the National Council for Culture, Arts and Heritage in Doha (Islamic Coins Centre), under the supervision of Ibrahim Jabir al-Jabir, with text and coin photographs by Ahmad Hamad al-Musa and Amal Sarhan. ^{3 1}

• What Islamic numismatics is: it says Muslims used Persian and Byzantine coins until Abd al-Malik ibn Marwan struck an independent coinage in 77/696, that scholars found coins shedding light on history not found in books and used them to correct common errors, and it explains the origins of the words dinar, dirham and fals. ²
• Coins by dynasty: from Sasanian and Byzantine coins and the reform issues, such as a dirham of Qatari ibn al-Fuja'a of 75 AH and Abd al-Malik's dinar of 77 AH, to the Umayyads, Abbasids, Tulunids, Ikhshidids, Hamdanids, Fatimids and Sulayhids, the North African states (Idrisids, Aghlabids, Almoravids, Almohads, Hafsids), the Ayyubids, Mamluks and Ottomans, and the Buyids, Samanids, Ghaznavids, Ghurids and Ilkhanids. ^{4 5 6 7 8 9 10 11}
• Weights and measures: citing Father Anastas Mari al-Karmali's book on Arab coins, it gives the canonical dirham as ten dirhams to seven mithqals and the mithqal as seventy-two barley grains, and introduces the glass weights that kept standards fixed. ¹²
• Gulf coins and the Saudi era: the larin (malawiyat), the Maria Theresa thaler countermarked for Najd and Hijaz, and the rupee countermarked "Najd". ^{13 14}
• Propaganda coins: coins carrying a political or publicity message. ¹⁵

The booklet states some judgements in general terms, for instance calling coins "important documents beyond doubt or challenge". ² Some of its dates are evidently loose, such as dating the Maria Theresa thaler to 1780 alongside King Abd al-Aziz, which is the date of the original type rather than of the countermark. ¹³
