1 Thaler - Edzard II, Christoph and John

East Frisia's coinage in the 1560s reflects the county's fractious dynastic politics almost perfectly. Edzard II, Christoph, and John were the three surviving sons of Edzard the Great, forced by inheritance custom to rule jointly — an arrangement none of them welcomed. The triple-named thaler is a direct artifact of that uneasy co-regency, struck to assert collective legitimacy at a moment when the brothers were actively disputing territorial division among themselves.

The joint reign effectively ended with the 1566 partition. Thalers naming all three rulers span only a narrow window, which keeps surviving examples thin on the ground.
