Thanks for this very informative thread, and those maps are excellent! This part of history is not very clear. To me it is no small wonder, that 'Soter Megas' real name may have been found! His coinage is rather common, but I'm happy we can call this Great Savior now by his first and last name Vima Takto. Here's my one coin of his. It has ten rays but no very clear lettering. 19 mm, 8.41 gr. MACW 2939. And I have these coins of the Yueh-Chih, it's an imitation following the tetradrachms of Bactrian king Heliocles. An 'ugly' coin of bad metal, not copper but an unclear mix that's prone to rust. Quite special, though. Large, heavy coins of 26-28 mm and 10-14 gr.
