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.
List of rulers of Monaco
François Grimaldi seized the Rock of Monaco in 1297, starting the Grimaldi dynasty, under the sovereignty of the Republic of Genoa. The Grimaldis acquired Menton in 1346 and Roquebrune in 1355, enlarging their possessions. These two towns (some 95% of the country's territory) were eventually ceded to France in 1861, according to the Franco-Monegasque Treaty.
