50 000 Marks

The Polska Krajowa Kasa Pożyczkowa — the Polish State Loan Bank — was a creature of the German occupation administration, established in 1916 to replace Russian currency in the occupied territories. By 1922, it was still issuing notes, but Poland's hyperinflationary spiral was already making large denominations obsolete almost as fast as they could be printed. A 50,000 Mark note that would have been a substantial sum in 1920 was worth next to nothing by mid-1923.

The series was printed domestically in Warsaw, a deliberate assertion of printing independence from the foreign contractors Poland had relied on in the immediate post-independence years.
