PCGS VF-30 (illustrated above).  Ex - Paul Arthur Norris - Ira & Larry Goldberg Coins & Collectibles, Inc.'s "Pre-Long Beach Sale", September 23 & 24, 2002, Lot 42, illustrated, where it was described as follows: "PCGS graded VF-30. An extremely rare issue that Vlack states is represented by just 2 or 3 specimens. Breen estimated the population at 7 or 8 known when he published his mammoth Encyclopedia in 1988. Originally struck to pay the French soldiers in the Ardennes, and many were spent in Alsace, where they eventually ended up in Canada or the Louisiana Territory. Struck at the Metz Mint in France, and this is the first year of issue of this new design. We note minor surface roughness and a few small raised areas as this billion (mostly copper, 20 percent silver) issue was exposed to a damp climate at some point. Boldly struck with all the devices sharp and most of the lettering quite clear as well..."
