1 Goldgulden - Joachim I Nestor and Albert IV

Joachim I and Albert IV ruled Brandenburg jointly following the death of their father, John Cicero, in 1499 — an unusual co-regency that lasted only until Albert's death in 1513. The joint issue reflects the formal partition of administrative responsibilities under the Hohenzollern house, though Brandenburg was never actually divided territorially. These gulden follow the Rhenish standard established by the Electoral Rheinbund, to which Brandenburg's coinage was bound by treaty obligation rather than tradition.
