0 Euro - Gustav II Adolf Vasa

EuroSouvenir notes are collector items with no legal tender status, issued under a licensed scheme that uses genuine euro-format security paper and Oberthur's intaglio printing — the same French security printer responsible for banknotes across numerous African and European jurisdictions. The zero-denomination format was deliberately chosen to sidestep EU regulations prohibiting the production of euro lookalikes with assigned face values.

Gustav II Adolf, the Swedish king who intervened decisively in the Thirty Years' War in 1630, died at the Battle of Lützen in 1632 — one of the most consequential battlefield deaths of the seventeenth century. His commemorative presence on a French-printed souvenir note sold likely at a Swedish tourist site is the whole story here.
