The author wishes to express, first his obligation to the comprehensive list of modern European copper coins compiled by his friend Mr. Lyman H. Low, and published as the Official Catalogue of the Scott Coin and Stamp Company of New York. The lines of this valuable list have been followed, as representing the most convenient order, and at the same time guaranteeing that the coins treated of might readily be found on application to this and other excellent concerns, both in England and abroad.
The filling in of the outline thus provided has been accomplished, however, by reference to the author's own large collection, from which many of the illustrations are made, and to the excellent private numismatic library of an indefatigable London amateur, Mr. Thomas Pocock. To both of the foregoing gentlemen many thanks are therefore rendered.
