Check this link out. It has digital copies of old articles and books on numismatics. Theres four pages of it. Once the book opens up, click the book (even tho the curser still displays as an arrow), and the pages turn. There are a couple dead links I saw an ariticle in there from 1869..you can spend hours in there. http://www.digitalbookindex.com/_search/search010coinsa.asp
