1 Dicker Penning - Edzard II, Christoph and John

The "Dicker Penning" — thick penny — was a denomination peculiar to East Frisian coinage, issued during a period when the county was governed jointly by three Cirksena brothers: Edzard II, Christoph, and John. The joint rule arrangement, forced by inheritance convention rather than political harmony, was characteristically fractious; the brothers spent much of the early 1560s negotiating internal divisions of territory and revenue that would eventually partition the county.

The two-year window of 1562–1563 likely reflects the precise overlap before administrative separation made unified coinage impractical.
