250 Roubles Nikolaevsk-on-Amur

The Amur Gold Mining Company issued scrip in 1920 during one of the most violent episodes of the Russian Civil War in the Far East. Nikolaevsk-on-Amur was held by partisan forces under Yakov Tryapitsyn, whose occupation culminated in the systematic massacre of the town's population and the burning of the settlement to the ground in May 1920 — an event known as the Nikolaevsk Incident. Notes issued here that year exist in a narrow window between the collapse of conventional authority and total destruction of the town itself.

That this scrip survives at all is the real point of interest.
