Official Netherlands Euro coin set collection covering the years 1999 to 2004, issued in Brilliant Uncirculated (BU) quality and presented in their original official mint cards. This lot includes six complete annual sets, each containing the standard series of 8 euro coin denominations (from 1 cent to 2 euro). All coins feature the common Eurozone reverse with the twelve stars of the European Union, while the obverse displays the effigy of the reigning Dutch monarch, reflecting the continuity of the Kingdom of the Netherlands. The 1999–2001 sets represent the first Dutch euro issues, struck before and during the official introduction of euro coins into circulation, making them particularly desirable for collectors building an early euro collection.
