25 Roubles Far Eastern Republic

The Far Eastern Republic was a short-lived buffer state established in 1920 at Soviet instigation, designed to avoid direct confrontation with Japanese forces occupying the Russian Far East. Its paper currency was never backed by meaningful reserves — the republic's monetary system existed largely as a political instrument, and multiple overlapping series circulated simultaneously alongside Siberian, Soviet, and Japanese-backed scrip.

The FER was absorbed into Soviet Russia in November 1922, after Japanese troop withdrawals made the buffer fiction unnecessary. Notes from the 1921 issues had an extremely brief window of nominal validity.
