Depicts a crowned coat of arms dividing the denomination, the motto below.

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. The supporters of the coat of arms are depicted as two Friars Minor, each with hair, beard, and vestments, holding raised swords while standing on a ribbon bearing the motto: DEO JUVANTE.

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