Watch List notes:

BUWAYHID, RUKN AL-DAWLA, Donative half-dirham with broad margins, Madinat al-Salam 347h. OBVERSE: In inner margin: bismillah duriba bi-Madinat al-Salam sanat... (i.e. without name of denomination). In field: letters 'ayn and 'ra above, below religious legend: Mu'izz al-dawla | Abu'l-Husayn | Buwayh. REVERSE: In field, below name of caliph: Rukn al-dawla | Abu 'Ali | Buwayh. WEIGHT: 1.50g. REFERENCE: cf Treadwell Ms347G, dies O2/R2 for a gold coin struck from these dies. CONDITION: Extremely fine and apparently unrecorded in silver. The mint/date formula lacks the denomination and so would be suitable for striking both gold and silver coins. The gold specimen from these dies illustrated by Treadwell (Shamma 8207) also appears to be a half-dinar by weight, much as the present coin is intended as a half-dirham, although the broad outer margins are not visible on the gold striking. (700 - 1000 GBP)
