Watch List notes:

Fatimids. al-'Aziz billah. AH 365-386 / AD 975-996. AR Dirham (25mm, 2.37 g, 3h). Dimashq mint. Dated AH 368 (AD 978/9). Cf. Nicol 558 (dated AH 370). Some weak striking, edge ragged. Fine. Of the highest rarity, apparently unpublished.

While gold dinars from Damascus are known for the year AH 368 (Nicol 549), this appears to be an unrecorded date for silver dirhams.
