Yes indeed Dwayne...and I see all those coins listed as "Head of Herakles" but the story I came to believe was that Alex III was the first to put his image on a coin as he believed himself to be a god. To stop any outrage about it he draped his head with the lion skin as tribute to Herakles...

This is attributed as being Alexander draped in lion skin yet it is clearly the same person as listed as "head of Herakles"
It is interesting because we know and have found busts of Alex and know what he looks like, but clearly we have never seen Herakles in person. I am sure that its a debatable subject whether I look should look on the image as a deified Alex or as Herakles but I am convinced it is the former.
