The two listings represent the same article which appeared in the May 1998 edition of the Numismatist by George Fuld except that the former contains links to the images of the coins where as the latter has some of the images embedded into the body of the text. The latter one, therefore, will take longer to open up in your browser. Editor's Note: J575/P631 was found to have been struck with the original 1866 reverse used on J507/P591 and thus is likely a Mint product.
