Albert II, Prince of Monaco
As Monaco's head of state, Prince Albert II is depicted on coins, including collectors' coins, with very rare exceptions. One of the most recent examples is the €5 silver Prince Albert II commemorative coin, the first commemorative coin with his effigy on it, minted in 2008. On the obverse, the prince is depicted in profile with his name on the top of the coin. On the reverse, the Grimaldi coat of arms appears; around it, the words "Principauté de Monaco" (Principality of Monaco) also appear along with the nominal monetary value of the coin.As the prince, his official shortened title is "His Serene Highness Albert II, Sovereign Prince of Monaco"; this does not include the many other styles claimed by the Grimaldi family.
City-state
The Principality of Monaco is an independent city-state. Monaco-Ville (the ancient fortified city) and Monaco's well-known area Monte Carlo are districts of a continuous urban zone, not distinct cities, though they were three separate municipalities ("communes") until 1917. The Principality of Monaco and the city of Monaco (each having specific powers) govern the same territory. Though they maintain a small military, they would still have to rely on France for defence in the face of an aggressive world power.
