Watch List notes:

Cn. Plancius. 55 BC. AR Denarius (18mm, 3.91 g, 6h). Rome mint. Female head (Diana Planciana or Macedonia?) right, wearing causia / Cretan goat standing right; bow and quiver to left. Crawford 432/1; Sydenham 933; Plancia 1. VF, light porosity, stain on the reverse.

John Melville Jones, in A Dictionary of Ancient Roman Coins, writes that the female head on this coin is likely "that of the personification of Macedonia, where Plancius had spent part of his career."
