AYYUBID: al-Ashraf Musa II, 1250-1254, AV dinar (4.75g) (al-Qahi)ra, AH650, A-831, B-4, date confirmed by examination of the specimen illustrated by Balog, VF, RRR. Balog listed this as an issue of the Bahri Mamluks during the reign of Aybak, which is technically correct, but as it cites only his nominal Ayyubid overlord, without mentioning Aybak, it seems more appropriate to classify it as Ayyubid. Both preferences are acceptable.
Estimate: 1,500- 2,000 USD
