100 Markkaa, Sarja II 1918

This note was printed in 1909 but only entered circulation in 1918 under the designation Sarja II — the Finnish Civil War had created an urgent need to mobilize reserves that had sat unissued for nearly a decade. The White government's grip on the Bank of Finland meant these older stocks were released as legitimate tender while the Reds issued competing currency from territories they controlled, producing one of the stranger dual-circulation episodes in Nordic monetary history.

Notes that spent years in vault storage before sudden wartime release tend to show paradoxical condition: clean paper with sharp folds from hasty counting rather than gradual wear.
