100 Kronor

Pick 54 spanned two decades of issue, with Gustaf Vasa appearing on what was then Sweden's highest-denomination note in general circulation. Tumba Bruk, the Riksbank's own paper mill and printing facility southwest of Stockholm, has produced Swedish banknote paper since 1755 — one of the longest continuously operating security printing operations in the world. The integration of paper production and printing under a single state-controlled roof was a deliberate policy choice, insulating the currency from foreign supply chain vulnerabilities that had complicated earlier Swedish monetary history.

Later printings in the series introduced a metallic security thread, replacing the earlier embedded plain thread — a distinction that matters for precise dating within the type.
