1 Ducat - Ernest August I Constantine

Ernest August I Constantine ruled Saxe-Weimar-Eisenach from 1728 until his death in 1748, making the date range here immediately puzzling — posthumous ducats struck under his name persisted into the reign of his successor Ernst August II, a not uncommon practice in small German courts where die inventory was conserved long past a ruler's death. The duchy was perpetually cash-strained, and recutting or retiring perfectly serviceable gold dies represented an unnecessary expense.

Fr#3033 alignment with Koppe's SW#490 confirms this as the standard ducal weight issue, not one of the rarer multiple-ducat presentation pieces occasionally struck for diplomatic gift-giving at the Weimar court.
