1 Groten - Gerhard VI

Gerhard VI ruled Oldenburg through a period of persistent friction with the city of Bremen and shifting alliances across the North Sea coastal territories. The groten was a north German denomination derived from the grossus tradition, and Oldenburg's counts used it as much for political signaling as for commerce — asserting comital monetary authority in a region where episcopal and municipal mints were constant rivals.

The forty-year span of this type reflects either a long-lived die use or reissues under the same nominal type, a common practice among smaller German territorial mints that lacked the volume to justify frequent die changes.
