That's a lovely coin. The lion/star must be a stylistic derivative of the lion/star designs of Miletus, no? The
standard Milesian
reverse for at least 400 years is a standing
lion with
head turned back, looking at a star/sun. (The difference here is that the
lion is running and facing forward.) Panticapaeum was founded as a Milesian colony around 600BC.
Does anyone happen to know of other lion/star coins?
