Watch List notes:

Abbasid, al-Wathiq (227-232h), silver 'dinar', Marw 237h, obv., without name of heir, rev., citing al-Wathiq billah, 2.86g, obverse double-struck, fine and unusual. This curious piece is presumably a contemporary imitation, given that denomination is given as al-dinar, the date is impossible for the caliph, and the module of the coin much smaller than official Marw dirhams of this period. Ex Samir Shamma Collection.
