This coin has been struck with exceptionally beautiful and delicately engraved dies. It is considered to be one of the true classics of ancient Greek coinage and has a worthy place in the cabinet of any discerning collector; indeed, many of the great collections of the 20th Century contained an example. The quadriga on the obverse, exceptional for its three-quarter perspective, has been captured in a composition of great complexity and imagination by the master artist Euth... It is also fascinating to consider the possibility that the artist of the reverse die, Phrygillos, could have been the same individual who was a noted engraver of precious stones.
