Watch List notes:

ABBASID: al-Mustadi, 1170-1180, AV dinar (1.01g), Madinat al-Salam, AH(56)8, A-267, remarkably thin flan, clear final digit of date and first part of "sittin" for "60", VF to EF, RR. This piece is much nicer than the usual examples of this caliph's coinage, which is almost always carelessly struck on remarkably thin flans.

Estimate: 700-800 GBP
