Not an area I'm well versed in, but I believe it's from Taxila, c. 200-100 BC. It seems a bit light for the 1.5 karshapana standard, but Greek or Scythian coinage would usually have a legend.
The obverse is a cow or zebu, I think with a Taurine (nandipada) symbol in front, and the reverse is a Chakra wheel.
