In honour of the 200th anniversary of the Battle of Waterloo, the government of Belgium announced plans to issue 2 euro coins celebrating the event. The government of France objected noting that the coin contained 'a negative symbol' for some Europeans and 'that the battle was an event with particular resonance in the European collective memory and went beyond being merely an instance of military conflict'. This objection left the Belgians in a bit of a problem as they had already minted 175,000 coins. They noted that the French sell commemorative coins at Waterloo. The Belgian government have now announced today that the coins would be issued as commemorative coins and are now worth 3 euros. Commemorative coins do not require any approvals from other countries. Last year France issued 2 euro coins celebrating the 70th anniversary of D-Day without any objections from Germany. The Germans apparently do not care about the change in their pockets.
