1 Thaler - Ferdinand I

Ferdinand I died on July 25, 1564, making this a posthumous or terminal-year issue struck in the final months of his reign — he had ruled as Holy Roman Emperor since 1558 after his brother Charles V's abdication. The Silesian mint operated under complex overlapping authorities during this period, with the estates of Silesia maintaining considerable independence in monetary matters even as Habsburg centralization pressed inward. Ferdinand had spent much of his reign trying to impose uniformity on the notoriously fractious Silesian minting apparatus, with limited success.
