750 Roubles

The Khorezm People's Soviet Republic had a brief and chaotic existence — declared in 1920 after the Red Army ousted the Khan of Khiva, it was absorbed into the Soviet Union by 1924. This 750 Rouble denomination is notably unusual: most emergency issues of the period gravitated toward round figures, and 750 suggests the denomination was calibrated against specific local exchange conditions or existing coinage equivalencies rather than simply copied from Russian Soviet practice.

Khorezm issued its own currency series precisely because monetary integration with Moscow was incomplete during the transition years. These notes circulated in a region where barter and silver coin remained dominant, and paper acceptance was far from guaranteed.
