100 Roubles Control Stamp - Type 1

In 1918, the Chita branch of the State Bank found itself operating under the authority of the Far Eastern government while the civil war fragmented Russia's currency supply beyond any central coordination. Rather than print new notes outright, branches like Chita resorted to overprinting existing Imperial or Provisional Government issues with control stamps — a quick administrative fix to distinguish locally authorized currency from the flood of competing emissions circulating across Siberia and the Russian Far East.

Type 1 distinguishes this stamp variant from at least one subsequent overprint iteration applied to the same base denomination, suggesting the branch revised its authentication method mid-issue — a detail worth tracking when attributing examples to specific circulation windows.
