The collection of paper money consists of banknotes and securities of Poland and neighbouring countries. The collection came to existence mainly on account of donations and also, in 1980s, not numerous purchases. Precious objects of the collection are first Polish banknotes printed during the Kościuszko Uprising in 1794. The most numerous among Polish paper money are collections from the interwar period and the times of Polish People’s Republic. They were Polish marks issued by Polish Loan Bank and the notes of the National Bank of Poland. A point of interest is a considerably numerous collection of paper money substitutes, issued by local authorities or private issuers. The most numerous are, however, city bonds issued by city halls and district offices in the lands of former Prussian Partition, German Reich and Austria.
