Antimachos I - Heads Or Tails?

Well anyone who follows my threads knows I recently picked up an Antimachos I drachm in fairly deceny condition with very near complete legends. Now I know there are people out there who know more then I about the Indo-Greek Kingdoms, and there coinage. I have a few pieces from this area, and none like this. I know its not really of consequence but I figured I would pose the question to those out there.What do you guys think the obverse or reverse is supposed to be. Not literally what the images are but which image is the obverse and which one is the reverse. Traditionally the Indo-Greek kingdoms featured coins similar to that of the Seleucids. A veneration of the king on the obverse with a Greek legend, and on the reverse one of the Gods sacred to the area and or peoples. This coin is a bit different. The "obverse" features what presumably is Antimachos on horseback with Macedonian hat complete a Kharosthi script In this case Maharajasa jayadharasa Antimakasa. On the "reverse", the Nike (Victory) on the reverse with a Greek legend, naming the king and title- in this case BASILEWS NIKYFOROU ANTIMAXOU, This seems to be the reverse of what is usually seen on the coins of the other kings. I wonder the seller (who is an expert in oriental and Indian coins) states that the coin was minted during the Greek invasion and occupation of Gandhara and Taxila (North West India and Pakistan) The coin is similar in style to the later Indo-Scythian kings. That series features a king on horse back on the "obverse" with Greek legends naming the king and title. The reverse features the deity/ god and the Kharosthi script on the "reverse". This is consistent with most other coins of the period yet mine is in conflict. I wonder if this was some how a reflection of the geopolitical situation at the time? Was the coin ment to exact fear in the populous so far from the Greek world? Was the king holding himself second to the Nike, as this would have been the "obverse" feauting the Nike advancing with Palm...Please let me hear what you think...and make heads or tails of this coin? (no pun intended)...

All guesses educated or not are welcome as well as any comments, suggestions, additions or corrections are always welcomed...drool is cool too...

Oh yea my photo (as it is in hand now...and awesome)
