1 Gulden - Romanus

Saint Blaise (Sankt Blasien) was a Benedictine abbey in the Black Forest whose abbots held the status of imperial princes, giving them the right to strike their own coinage — a privilege exercised sparingly and producing issues that today survive in very small numbers. The abbey's minting activity in the late seventeenth century coincided with efforts to assert and formalize its territorial authority following the disruptions of the Thirty Years' War.

A copper gulden is an unusual denomination; gulden were conventionally silver, and a copper striking at this face value suggests either a currency emergency or a token-style issue for local circulation within the abbey's immediate domains.
