Heracles was a divine hero in Greek mythology, the son of Zeus and Alcmene. He was the greatest of the Greek heroes, a paragon of masculinity, the ancestor of royal clans who claimed to be Heracleidae and a champion of the Olympian order against chthonic monsters. In Rome and the modern West, he is known as Hercules, with whom the later Roman Emperors, in particular Commodus and Maximian, often identified themselves.

Value divided by a sword facing upwards in the centre and shield below it. Mint marks on both sides of the shield. "Land Credit of Monaco" written in French at the top, "Good for fifty centimes" written at the bottom.

The shield is "blazoned" (described in the technical language of heraldry), fusily (or lozengy) argent and gules. The lozenge in heraldry is a diamond-shaped charge (an object that can be placed on the field of the shield), usually somewhat narrower than it is tall.
