Ecu 'Vertugadin' - Louis XV

The "Vertugadin" nickname derives from the pronounced convex bulge on the coin's edge — a farthingale, the hooped underskirt fashionable two centuries earlier — which resulted from a modified collar design introduced at the Paris mint in 1715 to reduce edge-splitting during striking. The experiment was short-lived. By 1718 the collar was abandoned, making this a technically transitional type produced entirely within the regency of Philippe d'Orléans, who assumed power following Louis XIV's death in September 1715 before the young king could rule independently.

The three-year production window is narrow enough that surviving examples frequently bear evidence of the mint's adjustments mid-run.
