Monaco has issued two different series of euro coins, one in 2002 and one in 2006.
The 2002 series features the effigy of His Highness Prince Rainier III on the €2 coin, and the effigies of Prince Rainier III and his son Prince Albert II on the €1 coin. The 10, 20, and 50-cent coins reproduce the seal of the Prince of Monaco, and the 1, 2, and 5-cent coins show the coat of arms of the Sovereign Princes of Monaco.
Following the death of its Head of State, Prince Rainier III, Monaco issued a new series of euro coins in 2006. The portrait of His Highness Prince Albert II features on the €2 and €1 coins, and his monogram is depicted in the 10, 20, and 50-cent coins. As in the 2002 series, the 1, 2, and 5-cent coins show the coat of arms of the Sovereign Princes of Monaco.
In both series, the edge lettering on the €2 coin is ‘2**’, repeated six times, alternately upright and inverted.
