Heres a coin I was considering to get ID'd using help from here, but then I barely read the ΔΙΟΔΟΤΟΥ on the reverse legend. A bronze, possibly also from Ai khanoum, of the Bactrian king Diodotus II (or I?) Diodotus I rebelled against the Seleucids and established the Graeco-Bactrian kingdom, and then Diodotus II was his son who reigned from around 235-225BC till he was murdered by the usurper Euthydemos I, (whose coins ill share in another post) My favorite thing about these bactrian bronzes are their beveled edges and flat reverses. Almost like a plano-convex lens. Heres the crusty coin, thats artemis advancing with a torch. Also the wikipedia of diodotus II has what I think is a very heavily tooled coin
To complement yours, here another one. Also not mother's finest, but far better looking than that tooled one.
