Brilliant, Saro. It's not the same coin as the one I indicated upthread (Hamadan mint, 10.7 grams) but, like the two others much like a known Iranian coin. I quote KM again:
As a result of the frequent recoinage of copper and its frequent demonetization, copper coins were not hoarded or saved and are consequently quite scarce today. Annual change meant that each mint had a multiplicity of types and varieties, most of which are uncommon today. The following listings are not an attempt at completeness, but give a representative selection of the products of each mint.
