Watch List notes:

ISLAMIC COINS, ABBASID, temp. al-Rashid, Gold Dinar, no mint, 191h, initial R, 4.23g (A 218.5; Bern 72). Hairline scratch on the reverse, otherwise extremely fine, scarce.
Album interprets the letter R as the mint Rafiqa whereas Bernardi, perhaps more convincingly, suggests it stands for Rashid and lists the coin alongside the issue with the initial H for Harun.

Estimate: £250-300
