Heracles shooting bow on his one knee right of the crowned monogram of Louis II, surrounded by the inscription "Heracles Monaco". Date below. Engraver's name is at the bottom left side.

The Grimaldi motto, Deo Juvante, is Latin for "With God's help", under the monogram.

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

The coat of arms of Monaco serves as the symbolic representation of the House of Grimaldi, the reigning sovereigns of Monaco. It incorporates elements such as the Franciscan Friars, the crown, the collar of the Order of Saint Charles, and a red and argent lozenge, all of which hold historical significance dating back to events relevant to their ascendancy as rulers of Monaco since the 13th century.

Thunderbolt mintmark of Poissy at the left of the shield.
