Three official Belgian Euro year sets for 2002, 2003 and 2004, issued in Brilliant Uncirculated (BU) quality and presented in their original folders by the Royal Belgian Mint. Each annual folder contains: - The complete set of 8 circulating euro coins (1 cent to 2 euro) - An official commemorative medal issued exclusively with the year set The circulating coins feature the effigy of King Albert II (first Belgian euro portrait type, used 1999–2007) on the obverse and the common European reverse with the twelve stars of the European Union. The commemorative medals are specially struck for the annual BU folders and are not intended for circulation. They are produced in medallic finish and highlight national themes related to Belgium and the introduction of the euro, forming an integral and collectible part of the official year sets. These medals were only available within the original folders, increasing their desirability for complete-set collectors. The 2002 set marks Belgium’s first year of euro circulation — a key historical issue. The 2003 and 2004 sets continue the early euro period prior to later design updates. All coins and medals are carefully preserved in their original official packaging. An attractive early-euro Belgian lot, ideal for collectors seeking complete official year sets including the original commemorative medals.
