Watch List notes:

Banijurid, Ahmad b. Muhammad b. Yahya (c.295-297h), Dirham, Andaraba 296h, citing the Samanid ruler Nasr II b. Ahmad (sic), 4.03g (SNAT XIVc:94 var. [same obv. die]; W 1479). Flat in parts otherwise about very fine, very rare.

Presumably a mule struck after 301h from an old obverse die.
