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.
Rainier III, Prince of Monaco
Rainier was born at Prince's Palace in Monaco, the only son of Prince Pierre of Monaco, Duke of Valentinois and his wife, the Monegasque Hereditary Princess, Charlotte, Duchess of Valentinois. Rainier was the first native-born hereditary prince of Monaco since Honoré IV in 1758. Rainier's mother was the only child of Prince Louis II of Monaco and Marie Juliette Louvet; she was later legitimized through formal adoption and subsequently named heir presumptive to the throne of Monaco. Rainier's father was a half-French, half-Mexican who adopted his wife's surname, Grimaldi, upon marriage and was made a prince of Monaco by Prince Louis, his father-in-law. Rainier had one sibling, Princess Antoinette, Baroness of Massy.
