Henri III gold Ecu d'or au soleil 1589-A/C UNC Details (Peckmarked) NGC, Compiègne mint, 3.32g, Fr-386, Dup-Unlisted (cf. Dup-1120 for type in Double Ecu weight). Of the greatest rarity, this one-year type was issued illegally in tiny numbers at the Compiègne mint to the north of Paris. The mintmarks are an "A" in the obverse exergue and a "C" at the end of the reverse legend. Although slightly doublestruck on the obverse and bearing a small test mark on the reverse, the coin remains quite lustrous beneath light tone.
