1738-Y Sou Marque. Bourges Mint. Vlack-217. Rarity-8. VF Details--Environmental Damage (PCGS). 31.7 grains. First year of issue for this extremely rare mint in the sou marque series, for which Robert A. Vlack reported only five specimens of all dates in his 2004 reference on the French billon coinage in the Americas. This richly toned example is predominantly deep olive-gray, although splashes of dark steely-charcoal associated with light surface encrustation are scattered about to explain the PCGS qualifier. Boldly defined overall with all major design elements fully appreciable. PCGS# 919609. To view supplemental information and all items from the Sydney F.
