This is a list of series of designs on the national sides of Euro coins.
Reasons for changes
Changes to the design of the national sides are generally not permitted until 15 years has elapsed. One major exception is for coins that depict a head of state, usually a monarch, which may change when the head of state changes. New coins for these reasons were introduced in Monaco in 2006, Belgium and the Netherlands in 2014, Spain in 2015, and Vatican City in 2005, 2006, and 2013. The 2006 Vatican City coins featured the symbols of the interregnum period, known as sede vacante, leading to a regulation banning nationals sides representing a vacancy or provisional occupant in regular coinage.
In some cases, national sides were changed to conform to new regulations. Changes in Belgium in 2008 and Spain in 2010, were in response to a new regulation that national elements could not appear in the ring of twelve stars on the outside of the design. A 2007 change in Finland was in response to the requirement for the country's name or abbreviation to appear on the coin.
As the earliest Euro coins were issued in 2002, some countries became eligible to change their designs in 2017. San Marino was the first to do so, in 2017. France revised the design of their €1 and €2 coins in 2022, and the 10c, 20c, and 50c coins in 2024. Belgium had violated this rule by using a new portrait of King Albert II as part of their 2008 design change, and was forced to revert to the original portrait the following year. A 2017 change was also made in the Vatican City coin, changing from a bust to a monogram.
