Watch List notes:

ABBASID: al-Muqtadir, 908-932, AR ¼ dirham (0.96g), NM, AH298, A-246B, decent strike, blackened surfaces, appears to have had a mount gently removed (barely noticeable), Fine, RRR. The weight is too heavy for a quarter dirham, appropriate for a third dirham, but as the weight of the donative pieces can vary considerably, the actual "denomination" is unclear and may be irrelevant.

Estimate: 200-250 USD
