100 Markkaa

Pick 13 was introduced as Finland moved toward a more assertive monetary posture under the autonomous Grand Duchy framework — still nominally under Russian imperial authority but operating its own currency through Suomen Pankki, which had functioned as a central bank in all but name since the 1860s. The 100 Markkaa denomination was the largest in everyday commercial use, and this series would remain in circulation well past the 1917 independence declaration.

Collectors should note that the series spans a wide date range and that later printings within the P13 type show subtle typographic differences in the serial numbering — enough to matter for variety collectors, not enough to affect general catalog pricing.
