Belgium's euro coins were designed by Jan Alfons Keustermans, Director of the Municipal Academy of Fine Arts of Turnhout. There are two series of coins in circulation. Both are valid.
The first series depicts King Albert II in the inner part of the coin, while the royal monogram - a capital "A" underneath a crown - among 12 stars, symbolising Europe, as well as the year of issuance appear in the outer part.
In 2008, Belgium slightly modified the design in order to comply with the European Commission's guidelines. The coins of the second series also show King Albert II, but the royal monogram and the year of issuance now appear in the inner part of the coin, as do the mint marks and the country code for Belgium, "BE".
Yvette Gastauer-Claire designed the coins by agreement with the Royal Household and the Luxembourg Government.
All the Luxembourg coins bear the profile of His Royal Highness Grand Duke Henri. They also bear the year of issue and the word "Luxembourg" written in Luxembourgish ("Lëtzebuerg").
There are two series of coins in circulation.
The first series depicts, on the €2 coin, HSH Prince Rainier III. A double portrait of HSH Prince Rainier III and HSH Hereditary Prince Albert appears on the €1 coin. The 10, 20 and 50-cent coins depict the Prince’s seal. The coat of arms of the Sovereign Princes of Monaco is shown on the 1, 2 and 5-cent coins.
The second series shows, on the €2 and €1 coins, a portrait of HSH Prince Albert II. HSH Prince Albert’s monogram is depicted on the 10, 20 and 50-cent coins. The coat of arms of the Sovereign Princes of Monaco is the main feature of the design on the 1, 2 and 5-cent coins.
There are three series of Vatican City coins in circulation.
The first series, bearing the effigy of His Holiness John Paul II, was issued between 2002 and 2005.
The second series, first issued in June 2005, shows the coat of arms of the Cardinal Chamberlain, the interim Head of the State of Vatican City, superimposed on the emblem of the Apostolic Chamber in the centre of the coin. The upper part of this design is surrounded by the semicircular words "SEDE VACANTE" and the year of issue in Roman numerals, i.e. "MMV". The mintmark ("R") is located between the coat of arms and the year of issue. The designer's name, "D. LONGO", appears on the lower left-hand edge of the central design, while the respective engraver's initials appear on the lower right-hand edge, namely "MAC inc" (on the 1 and 20-cent coins), "LDS inc" (on the 2 and 50-cent coins), "ELF inc" (on the 5 cent and €1 coins) and "MCC inc" (on the 10 cent and €2 coins). Twelve stars are depicted in a semicircle around the upper half of the outer edge of the coin, while the lower half bears the words "CITTÀ DEL VATICANO", again set in a semicircle.
The third series, issued in April 2006, shows His Holiness Pope Benedict XVI and the legend "CITTÀ DEL VATICANO". To the right of his portrait are the year ("2006") and the mint mark ("R"). To the left are the designer’s initials ("DL").
