It's a funny article and great "coin", but @randygeki beat you to the punch a couple of weeks ago https://www.cointalk.com/threads/tooled.285159/
Ancient Noob put his conehead coin here without any explanation. But this was actually the fashion ideal of this era. Several central Asian "Hunnic" tribes bandaged the heads of the children of the nobility from an early age to achieve something like this shape. (Inspired by the aliens, ofcourse)
Not just the Huns, some ancient cultures in Peru also did this. Which clearly proves, of course, that ancient aliens visited ancient Peru, inspiring the skull-shaping fashion while they helped the locals make the massive stone structures of Machu Picchu, Sacsayhuaman, etc. (When I was in Peru in 2011, I asked my tour guide if he had ever heard of these crazy "ancient alien" theories. He had, and said that he found them not just foolish but insulting to his ancestors: the unspoken implication is that ancient Peruvians weren't clever enough to figure out how to move and work large stones without outside help. Nobody ever seems to think that aliens were required to build the Parthenon, or the Coliseum.)
I believe also, that the Flathead Indians in the Northwest US / British Columbia area of Canada also shaped their skulls since a baby. Just odd how folks need to associate totally outside forces to issues that are "unexplained".
