Jacob Leer The Seal and Coat of Arms engraver Jacob Leer was appointed in 1659 as die cutter for the Cologne Circle, Germany. In May 1680 Jacob Leer was admonished by the Lower Rhine-Westphalia Circle for cutting dies for the Cologne Archbishopric Mintmaster in Dorsten without permission. Leer was most likely the die cutter for an Archbishopric of Cologne 1693 gulden because of the similarity with the workmanship on a ducat that he cut. Noted by Scheffler as Jacobus Leher with the alternative names Leer, Lyher and Lier.
