3 Roubles

Tannu Tuva's 1925 banknote series was issued by the People's Republic of Tannu Tuva, a Soviet client state wedged between Siberia and Mongolia that most of the world did not recognize as independent. These notes were printed in the USSR, effectively making the currency a Soviet administrative product for a nominally sovereign territory. The 3 Rouble denomination mirrors the Russian ruble structure directly — the entire series was pegged to Soviet monetary conventions rather than any indigenous financial system.

Tuva was formally annexed by the Soviet Union in 1944. Notes from this 1925 series had a circulation window of roughly two decades before the territory ceased to exist as a political entity.
