In 1752 Collin married and settled in Nancy, where he soon acquired a reputation, and was named engraver to the town, and also to the King of Poland, Stanislas, Duc de Lorraine et de Bar. He died in Nancy, December 21st, 1781. He produced more than 300 engravings, on many of which he signed himself “graveur du feu roi de Pologne.” A catalogue of his works was given by Mons. le Conseiller Beaupré in “Les Mémoires de la Société d’Archéologie Lorraine,” and a supplemental list, drawn up by Mons. A. Benoit, with illustrations, appeared in the “Archives de la Société Française,” April, 1895. His son, Yves Dominique Collin, also worked on book-plates, and, judging by the few known examples of his work, would probably have surpassed his father, but, unfortunately, his career was brief. He was born in Nancy, in February, 1753, and died in the same city on April 26th, 1792. He signed his plates _Y. D. Collin, fils._ The following is a list of the known book-plates of Dominique Collin; his mode of signature varied, and he spelt his name Collin or Colin indifferently. Bourgeois. Des Salles.
