FRANCE: 1 Ecu (1761 A) in silver (0,917). Head of Louis XV with headband facing left on obverse. Crowned round arms of France within sprays on reverse. Scratched on reverse (it is likely that the Mint made that scratches in order to remove metal and adjust the weight of such coins that were constructed overweight). Weight: 29,1gr. Engraved by Jean Dupeyron (Heron mark). (KM 512.1) & (Dav# 1331). Very Fine plus.
