Never seen a coin like this one.
India, local imitation of Apollodotus II, ca. 85-0 BC?
AR "drachm" 16mm, 0.92g
Degenerate head right wearing diadem, garbled legends
Bottom part of Athena Alkidemos, Kharosthi around, box monogram
Unpublished?

Anyone seen one like it before? I was tempted at first to think it was one of the rare, late Indo-Greek kings, but I think only Apollodotus II used Athena with that box-shaped monogram on the reverse.
The weight is also curious - less than half of what a drachm should weigh, and easily apparent from its very thin flan. This clearly wasn't meant to fool anyone, unless it was intended to be used as a hemidrachm?
