Oldenburg's coinage in the 1760s was produced under Frederick V of Denmark, who held the county as a personal possession separate from his Danish crown. The county's mint rights were administratively distinct from the Danish royal mint, which is why Oldenburg issues of this period carry their own local denominations rather than conforming to Danish monetary conventions.
The Mariengroschen was a north German denominational tradition with roots in the late medieval period, still circulating in small-state economies long after larger German territories had standardized around the Thaler system.
