Teston - Immobilization in the name of Charles V

Besançon occupied a peculiar constitutional position: a free imperial city within the Franche-Comté, technically subordinate to the Holy Roman Emperor yet fiercely protective of its mint rights against Spanish Habsburgs who controlled the surrounding county. The practice of "immobilization" — freezing the coin's nominal ruler as Charles V long after his 1558 abdication and death — was a deliberate legal fiction allowing the city to assert ancient imperial privilege rather than acknowledge the reigning emperor, sidestepping demands to update the type.

Production across this seventeen-year span coincided with the Thirty Years' War disrupting regional silver supplies and trade networks throughout Burgundy.
