Serain, a mint of the lords of Ligny—who became counts in 1367—located in the present-day French department of Aisne, near
Élincourt, where coins were struck by Walram II of Luxembourg, Lord of Ligny (1304–1353 and 1364–1366), possibly by his son
John I (1353–1364) and by John I’s grandson, Walram III, Count of Ligny and Saint-Pol (1371–1415).
