Watch List notes:

ABBASID REVOLUTION: 'Abd al-Rahman b. Muslim, 744-754, AE fals (2.57g), Jurjan, AH130, A-208A, citing only Abu Muslim (i.e., Abd al-Rahman b. Muslim), some weakness near the rim, 2nd known specimen, Fine, RRR. The first known example appeared in our Auction 29, Lot 139, for which I interpreted the words before the date as "bin muhammad", thus the patronymic after a name off flan. It is actually "âl muhammad", thus the last part of the ruler's titulature "abu muslim amir âl muhammad". The theoretical type A-F209 does not exist, and the date is AH130, not 137.

Estimate: 150-200 USD
