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.
Albert II, Prince of Monaco
As Rainier III's health declined, his son's lack of legitimate children became a matter of public and political concern owing to the legal and international consequences. Had Prince Albert succeeded his father and died without lawful heirs, it would have triggered Article 3 of the 1918 Franco-Monegasque Treaty, according to which the Principality of Monaco would become a protectorate of the French Republic. Prior to 2002, Monaco's constitution stipulated that only the last reigning prince's "direct and legitimate" descendants could inherit the crown.
