Watch List notes:

KHWARIZMSHAH: Muhammad, 1200-1220, AE jamshidi dirham (7.9g), Samarqand, AH616/610, A-1722, AH616 on obverse, 610 on reverse, but because engraver forgot to include sana on the reverse, actual date is 616, Very Fine, R. This example proves that all jamshidi dirham are actually dated 616, never 610.

Estimate: 130-150 USD
