1747/3-A Sou Marque. Paris Mint. Vlack-26b. Unique. First Semester. AU-58+ (PCGS).33.3 grains. The discovery coin for this overdate variety, and still unique, this is also a beautiful sou marque irrespective of Vlack number. Lustrous light silver surfaces retain full silvering. Minor planchet roughness (as made) in the center of the obverse obscures the detail in that area to a minimal extent, the strike well executed with most features crisp. A delight to behold, and eagerly awaiting inclusion in another world class cabinet of this French colonial series.PCGS# 169915.From the Sydney F. Martin Collection. Earlier ex Jeff Rock, September 2006. The plate coin for the variety in the 2004 Vlack reference on French billon coinage in the Americas.
