Sterling LVN TOL ЄNG IЄN

Elsen proposes that the unusual legends on both sides of this coin are explained by a monetary union between the Bishopric of Toul and the Duchy of Lorraine. It is known that such a union began between Bishop Odo III of Grandson and Duke Theobald II in 1308 (de Saulcy p. 47). Elsen points out the similarity in the legend on the cross side between this coin and the Sterling of Frederick IV of Lorraine (see link), suggesting the union persisted into that reign, which would correspond to the reigns in Toul of Bishops John of Arzilieres (1310-1321) and Amadeo of Geneva (1321-1330).
It was also likely known to the engravers of both coins that LVN TOL ... (on the Toul Sterling) and LON TOR ... (on the Lorraine Sterling) would closely mimic the mint name on the English penny which both of these were mimicking.
