500 Roubles Blagoveshchensk

The Blagoveshchensk Branch of the State Bank operated in genuinely unusual circumstances during this period — the city on the Amur River changed hands multiple times between Bolshevik, White, and Japanese-backed forces between 1918 and 1920, and local branch issues like this one were a direct consequence of the complete breakdown in currency supply from central authorities. Regional branches across Siberia and the Far East were effectively forced to act as autonomous issuers, with little coordination and no consistent redemption guarantee.

The Pick S-prefix designation places this firmly in the Siberian and Far Eastern emergency issues — a category notorious for attribution difficulties, given how many branches issued notes under nearly identical institutional names with overlapping date ranges.
