Fatimids. al-Mu'izz li-Din Allah. AH 341-365 / AD 953-975. AR Narrow Dirham (19.7mm, 2.20 g, 12h). Al-Mansuriya mint. Dated AH 343 (AD 954/5). Cf. Stephen Album Rare Coins 37 (11 June 2020), lot 383; cf. Nicol 464 (date missing). Dark patina. VF. Very rare.
This piece has been struck from dies similar to those used for normal half-dirhams, but the flan is markedly thicker and the coin itself is heavier. These so-called 'narrow dirhams' are now known for the mints of Barqa, Misr and al-Mahdiya as well as al-Mansuriya. All are rare.
