1 Ducat - Gustav Adolf II

Gustav Adolf was killed at the Battle of Lützen on November 6, 1632, making any ducat struck that year a coin produced during the final months of his reign — though he almost certainly never handled one. Swedish ducats of this period were primarily struck for diplomatic gift-giving and payment of foreign mercenary officers rather than domestic circulation, which explains the consistently high technical quality found across survivors.
