25 Roubles

Finland at this date was an autonomous Grand Duchy under the Russian Empire, and the Bank of Finland issued notes denominated in Russian roubles rather than any distinctly Finnish unit — the markka wouldn't arrive until 1860. This note belongs to the period when Finnish monetary affairs were effectively subordinated to St. Petersburg's currency system, though the Bank of Finland itself retained institutional independence unusual for a territory in its political position.

The sixteen-year issue window suggests these notes were reprinted across multiple runs rather than produced in a single series, with date ranges that can help narrow individual examples to specific emission periods.
