Abbasid: al-Muqtadir (908-932), silver dirham (3.03g), Tiflis (Tbilisi, Georgia) mint, AH 312 (924-925 CE). Album - (unpublished). Extremely fine. Extremely rare. Unpublished. Compare with similar specimen in lower condition that sold in SARC auction 53 for $1680 USD (including premium). This remarkable dirham also does not cite heir Abu al-'Abbas, therefore not fitting the conventional references, including Album's type 246.1, which only occurs for earlier years AH 296-298.
