GREAT MONGOLS: Anonymous, ca. 1220s-1249s, AV dinar (3.15g), NM, AH628, A-A1967, citing the caliph al-Nasir li-din Allah on the obverse, the kalima on reverse, minimal weakness, VF, RR. The date is reasonably clear, especially "thamân" for "8", and the entire date is confirmed by this piece and lot 606, struck from the same dies, with "20" fully legible. The last digit for "600" is very clear on this piece, weak on lot 606. The comparison of these two piece confirms that there is no mint name on this subtype.
Estimate: 300-400 USD
