This is one of the few ancient coins that my wife actually likes, on account of the wonderfully charismatic goat (see detail pic). Oversized flan, and so deeply toned it looks bronze.

According to Seaby: "In the temple of Vejovis in Rome, there stood near his statue a goat bearing a winged Genius on his back, a representation of which recalls the infancy of Jupiter who was suckled by the goat Amaltheia on Mount Ida."
