100 000 Marks

The Polska Krajowa Kasa Pożyczkowa — the Polish State Loan Bank — was not a central bank in any orthodox sense but a wartime financial instrument established under German occupation in 1916 to manage currency in the occupied Polish territories. It outlasted its origins considerably, continuing to issue marks well into the early 1920s as Poland struggled to assert monetary independence while hyperinflation gutted the denomination's purchasing power.

By the time this 100,000 Mark note was printed in 1923, the mark had collapsed so severely that the denomination was already near worthless. The zloty reform of 1924 terminated the series entirely, with 1,800,000 Polish marks converted to a single new zloty.
