50 Markkaa / Mark

Pick 107 belongs to the post-war series that ran through Finland's prolonged adjustment to the 1963 currency reform — the new markka revaluation that replaced the old markka at 100:1. Notes from this transitional issue carried dual-language denomination text in Finnish and Swedish, as required by constitutional law rather than commercial convention. The Bank of Finland's in-house printing works handled the entire run domestically, which was not always the case for earlier Finnish issues.

Serial number prefixes on this series can help narrow production batches, as the Setelipaino ran multiple print orders across several years under the same Pick number.
