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
The Grimaldis used the title of Lord until 1612. Then, Lord Honoré II started using the title of Prince, thereby becoming the first Prince of Monaco. Afterwards, Honoré II secured recognition of his independent sovereignty from Spain in 1633, and then from France by the Treaty of Péronne in 1641. Since then the area has remained under the control of the Grimaldi family to the present day, except when under French control from 24 February 1793 to 17 May 1814.
