GREAT SELJUQ: Barkiyaruq, 1093-1105, AV dinar (2.68g), Nishapur, AH486, A-1682.1, some weakness as usual, almost no wear at all, EF to About Unc, RR. Between 485 and 490, Nishapur first belonged to Malikshah I, who died in 485, then Mahmud I very briefly, then to Arslan Arghu in 486, then to Barkiyaruq 486-487, then once again to Arslan Arghu 487-489 or 490, then to Sanjar as vassal under Barkiyaruq. The final digit on this piece is weak, but can only be "6", as the final letter can only be "t" of 6, not "ayn" of 7.
