1/3 gros ou maille tierce

Issued under Eudes IV, Duke of Burgundy, whose reign saw the duchy at a territorial peak following his marriage to Jeanne de France and the inheritance of the County of Burgundy — effectively doubling ducal holdings. The maille tierce denomination itself was a fraction born of monetary practicality, filling the gap left by chronic small-change shortages that plagued French feudal coinage throughout the mid-fourteenth century.

The Dumas reference places this among several closely related varieties distinguished primarily by minor legend differences and billon alloy inconsistencies across minting sessions.
