Head of Athena left, wearing Corinthian helmet decorated with wreath; c/m: star, with pellets around, in incuse circle / Star between two dolphins. Holloway, Further, Series 4; CNS 62; HGC 2, 1436. Host coin Fine, green patina, encrustation; countermark Good VF. Interesting countermark, the pellets are around the periphery, but also flanking just one ray, suggesting the type might actually represent a comet.
