4 Ducats - Carl XI

Reval — present-day Tallinn — had been under Swedish rule since 1561, and by 1668 the city retained limited but meaningful privileges to strike its own gold coinage under Carl XI's authority. This four-ducat piece reflects that autonomy: a municipal issue from a Baltic port city that Swedish imperial administration had not yet fully absorbed into standardized crown coinage. Carl XI was still a minor in 1668, with the regency government of his mother Hedvig Eleonora effectively ruling. The coin's civic origin matters — Reval's minting rights were curtailed in subsequent decades as Swedish centralization tightened.
