6 Ducats - Maximilian I

The Teutonic Order's administrative seat had shifted to Mergentheim following the secularization of Prussia in 1525, and by 1603 the Order functioned primarily as a Catholic ecclesiastical institution under Maximilian I of Austria, who served as Grand Master from 1590 to 1618. Multiple-ducat presentation pieces of this weight were rarely struck for commerce — they served as diplomatic gifts and ceremonial payments within the Habsburg sphere, which explains why survivors overwhelmingly appear in cabinet condition.

Fr#3379d distinguishes this emission within a closely related sequence of Teutonic Order gold issues; collector confusion between the 'd' subtype and adjacent varieties is persistent and well-documented.
