Each member state of the Eurosystem can issue commemorative coins once a year (see the Commission Recommendation of 29 September 2003 - EU Official Journal 15/10/2003). Only the €2 denomination can be used for commemorative coins. They have the same features and properties and the same common side as normal €2 coins. What makes them different is their commemorative design on the national side. They are legal tender throughout the euro area and can therefore be used just like any other euro coin.
The Principality of Monaco, the Republic of San Marino and the Vatican City can also issue commemorative coins.
