Woudagemaal Vijfje 2020 UNC-quality in Coincard

The Royal Dutch Mint celebrates the 100th anniversary of the Ir. D.F. Woudagemaal: the largest, still functioning steam pumping station in the world. The Woudagemaal was opened in 1920 by Queen Wilhelmina, and its job was pumping excess water from Friesland into the Zuiderzee, and later into the IJsselmeer. To this day, the Woudagemaal still plays a crucial role within the Frisian water authority.
