Uncertain dynasty (possibly Buwayhid). AV Quarter-Dinar (14mm, 1.22g, 6h). Mint off-flan. Dated '86' (probably for AH 386 / AD 996). Legends similar to those used on Umayyad dirhams, with the Surat al-Ikhlas in reverse field. Loop-mounted. VF. Of the highest rarity and apparently unpublished.
Although this coin lacks the name of a caliph or any other issuer, the use of the Surat al-Ikhlas is characteristic of Buwayhid issues. A spectacular Buwayhid 10-dinar piece similarly copies Umayyad dirhams for its legends and design (vide Morton & Eden (London) auction 73 (23 April 2015), lot 166), and for a comparable silver fractional dirham vide Morton & Eden (London) auction 85 (27 April 2017), lot 534.
