1719 B ECU FRANCE
French ECU silver coin Louis XV's childhood design, Mint Mark B is Rouen. KM#435.3
It's a coin over 200 years ago, but it's a good one. I got it at the auction, but maybe the owner isn't very interested in it, I put it up as a medal in the North American corner, and the size of the photo is unknown, so I made a successful bid by myself. It's a story 20 years ago. The winning bid is 3000 yen.
