Watch List notes:

ARAB-ARMENIAN, TEMP. MUHAMMAD B. MARWAN, Drachm or 'zuzun', possibly Barda'a or al-Bab circa 73-74, in the name of Hormazd IV. OBVERSE: Bust of Hormazd IV to right with his name in Pahlawi before and afzwt behind; Inmargin: bismillah la i – laha illa Allah – wahdahu Muhammad – rasul Allah. REVERSE: Fire altar with attendants; šta to left, rabbi Allah to right. WEIGHT: 2.78g. REFERENCE: cf Sears 1-3. CONDITION: Toned, some deposit, good very fine, apparently an unpublished variety of this very rare issue. NOTE: Published examples of this type seem to have the denominational name 'zuzun' to the right of the fire-altar on the reverse, and rabbi Allah in the second quadrant of the reverse margin. The present coin omits the denomination and moves rabbi Allah to where 'zuzun' would normally be placed, leaving the reverse margin plain.

Estimate: £7,000-10000
