I've always thought these coins to be extremely attractive, and have often thought of acquiring one myself. The quirkiness of the obverse -- really, three guys marching lockstep in the same direction? -- combined with the artistry of the eagle on the reverse, make this coin simply fun to look at. Yours is a very high quality example.
Beautifull Koson Stater Orfew! I got one 2 years ago from Gorny&Mosch auction. Great for both of us, that someone found a small hoard of MS quality staters in Romania. Also, glad the govt. there did not seize them Mine was from Olbia Mint, yours too?
