1/2 Guldengroschen - John

The Ernestinian half-Guldengroschen series of the late 1520s was produced as the Electoral Saxon treasury scrambled to service an increasingly complex monetary economy — one being actively reshaped by the political fallout of the Reformation. John the Steadfast, Elector from 1525, was Luther's most consequential secular protector, hosting the Diet of Speyer in 1529 and financing the Protestant cause at considerable fiscal strain.

The Keilitz 96.1 variant designation signals minor die differences within the series, typical of multi-year runs across the Annaberg and Wittenberg minting operations during this period.
