1 Ducat - Gustav IV Adolf 3rd portrait

Gustav IV Adolf's reign ended in a military coup in March 1809 — officers who blamed him for the catastrophic loss of Finland to Russia deposed him in his bedchamber at Stockholm. His coinage was struck across a decade of near-continuous military humiliation, including the Finnish War and Sweden's forced participation in Napoleon's Continental System. The 3rd portrait ducat spans almost the entire reign, making terminus examples from 1808–1809 historically loaded pieces.

Fr#77 is the Friedberg reference for this type within the Swedish gold series. The .976 fineness is characteristically high for Swedish ducats of the period, a standard the Stockholm mint maintained with unusual consistency into the nineteenth century.
