The sheer number of recorded signature combinations on this note — over two dozen pairings across two State Bank directors, Eduard Pleske and Sergei Timashev — reflects a continuous print run spanning roughly a decade of active issue from 1898. The second signatory in each pairing was a cashier, and the rotation of cashier names documents staff turnover at the St. Petersburg office across that period. Collectors pursuing a complete signature set face a genuinely demanding task; some cashier pairings surface rarely.

Pleske directed the State Bank until 1903, when Timashev succeeded him — making the director's signature the cleaner dating tool when the printed year gives nothing away.
