10 Gulden Lieftincktientje

Named after Piet Lieftinck, the Dutch Finance Minister who ordered the post-liberation currency reform, this note was central to one of the most aggressive monetary purges in postwar European history. Introduced in September 1945, it was paired with a compulsory exchange program that effectively froze most of the old wartime currency in blocked accounts — wiping out a significant portion of the liquid wealth held by those who had profited, willingly or not, under the occupation.

Every household was initially permitted to exchange only 300 guilders. The rest went into blocked accounts subject to a capital levy.
