Oh okay. So its depending on what set of punch marks on on the coin corresponds to a ruler which can be dated.
well, here's my last surge coin. i get to check "western satraps coin" off the ol' list. Vijayasena AR drachm 17mm 2.3g o: bust of vijayasena, corrupt greek legend, date behind. 242 AD (162 saka era) r: hill and river with sun and crescent moons, Brahmi legend "Rajno Mahaksatrapasa Damasenasaputrasa Rajno Mahaksatrapasa Vijayasanasa" i believe this says something to the effect of..."son of king and great satrap damasena, king and great satrap vijayasena" if interested in the western satraps.. http://en.wikipedia.org/wiki/Western_Satraps if you want the quick version, here's the wiki map..
To me the Satraps coins always looked like the silent film villains who tie damsels to railroad tracks. Great summer coin surge Chris! Next up fall surge?
well, i'm doing summer surge part ii i think...budget bronze edition. i told the wagon what it could go do with itself .
