I did a search on this forum, but have not found this information. If I have duplicated this information, I apologize, but I find this a very helpful internet tool which can be educational for new and seasoned collectors alike. Unlike checking PCGS for prices and having to be a member, and getting a short preview, this part of the PCGS website so far, is not restricted. Here is a sub-link to the Photograde section for Jefferson nickels http://www.pcgs.com/Photograde/#/Jefferson/Grades but if you look at this page you can see all sorts of US coin Photograde helpful links. http://www.pcgs.com/Photograde/
