SAFFARID: Ahmad b. Muhammad, 923-963, AV dinar (2.33g), Zaranj, AH324, A-A1411, citing the caliph al-Radi, scruffy surfaces, at a weight that could be either a rather heavy fractional dinar, which can weight up to 2.5g, or a partly clipped down full dinar, which normally weighs about 3.5-4.5g., VF, RR. Likely a clipped full dinar, as the fractional dinar almost never has two marginal legends on the obverse!
