Fatimid, al-Mahdi (297-322h), sudaysi, al-Jaththa, undated, 0.29g (Nicol 8, citing a single example, very fine with mint-name particularly clear, extremely rare. Fatimid partisans were active in the Yemen during al-Mahdi's time. Album (Checklist, p. 118) notes that they appear to have gained control of several mint-towns in the region during the years 298-301h. Jaththa is the rarest of these, and the coin offered here appears to be the second published example of the type. The obverse margin on this piece gives the denomination as 'al-dirham'. (£1200-1500)
