Tonnerre's coinage rights were held by the counts under a series of contested agreements with the French crown, and the long attribution window here — stretching across a half-century that included the early Hundred Years' War and multiple French monetary ordinances — makes firm assignment to a single John difficult. Both John I (died 1309) and John II de Chalon presided over Tonnerre, and the overlap in their typologies has never been cleanly resolved in the literature. PA#5868 remains a working attribution rather than a settled one.
