This is again
Kushan or a derivitive. The
reverse is Siva standing in front of
his bull Nandi. What looks like a
head of a smaller person to the left of him is actually the hump on the brahman bull's back.
The
obverse has the
king standing, with a
standard and
altar in front of him, over which he is holding out
his hand.
Unfortunately there doesn't seem to be any
inscription to the right of the
king, so it is probably very late (c.3-400 AD.)
Mitchiner shows these anonymous
types in
his 'Ancient and Classical World', spreading the coins over the period c.250-360, but I understand that most experts would say they were unattributable to definite kings. I hasten to add that I don't consider myself to be any sort of an expert!
