1/2 Groschen - Odo IV shield of Burgundy

Historical Context: This 1/2 Groschen coin was issued by Odo IV (Eudes IV), Duke of Burgundy, between 1327 and 1330. Odo IV was a significant figure in early 14th-century French politics, a powerful vassal of the French crown. His marriage to Jeanne III, Countess of Burgundy and Artois, greatly expanded his territorial influence. The issuance of fractional Groschen coinage reflects a robust regional economy, requiring smaller denominations for daily commerce and indicating Burgundy's growing economic autonomy.

Artistry: The design of this 1/2 Groschen is characteristic of late medieval European numismatics, emphasizing heraldic clarity. Individual engravers are rarely recorded for this era; the style reflects the prevailing Gothic aesthetic, favoring strong lines and symbolic representation. The obverse prominently features the ducal shield of Burgundy, likely displaying the arms "bendy of six, or and azure, within a bordure gules," a clear dynastic statement. The reverse typically bore a cross or religious emblem, surrounded by a Latin legend.

Technical/Grading: Struck in billon with an impressive silver content of 700-800 parts per thousand, this 1.68-gram, 22mm coin represents a solid monetary standard for its time. High points susceptible to wear include the raised lines of the ducal shield, legend lettering, and any central cross design. Due to period minting techniques, examples often exhibit variable strike quality, including off-centering, planchet irregularities, or weak strikes. Collectors should examine shield details and legend legibility. References PA#5768, Barth#4/7, and Dumas#10-10-2 provide definitive identification.
