Watch List notes:

UMAYYAD: Marwan II, 744-750, AE fals (1.80g), Tiflis, ND, A-142T, Bennett-55, Zeno-45485, with the standard kalima divided between the obverse & reverse centers, the mint formula on the obverse, citing Marwan b. Muhammad in the reverse margin as al-amir, thus likely as governor of the Caucasus before achieving the caliphate in AH127, Fine, RRR. Bennet & Zeno both report only two known examples, and this is presumably the third; described in detail by Turkia and Paghava in ONS Journal #191.

Estimate: 400-500 USD
