Euro gold and silver commemorative coins are special euro coins minted and issued by member states of the Eurozone, mainly in gold and silver, although other precious metals are also used in rare occasions. Belgium was one of the first twelve countries in the Eurozone that introduced the euro ( ) on 1 January 2002. Since then, the Belgian Royal Mint have been minting both normal issues of Belgian euro coins, which are intended for circulation, and commemorative euro coins in gold and silver. These special coins have a legal tender only in Belgium, unlike the normal issues of the Belgian euro coins, which have a legal tender in every country of the Eurozone. This means that the commemorative coins made of gold and silver cannot be used as money in other countries. Furthermore, as their bullion value generally vastly exceeds their face value, these coins are not intended to be used as means of payment at all although it remains possible. For this reason, they are usually named Collectors' coins. The coins usually commemorate the anniversaries of historical events or draw attention to current events of special importance.
