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.
Succession to the Monegasque throne
Under the constitution of Monaco, the crown passes according to male-preference cognatic primogeniture. Only persons descended from the reigning monarch and the reigning monarch's siblings and their descendants, whose parents have been married at some point with the monarch's approval, and who are Monegasque citizens are eligible. Children born as a result of adultery are permanently excluded. A dynast forfeits succession rights if he or she marries without the monarch's permission, along with descendants of the unapproved marriage, but can be restored into the line of succession if the marriage produces no issue and ends before the demise of the crown.
