[QUOTE="Mark Feld, post: 646151, member: 11467"]I believe, that because each coin is unique, grading sets have very severe practical limitations. You can spend all day trying to match a given coin to one in a set, but there will always be differences, subjectivity, biases and inconsistency involved. Allowances are made for differences among various dates and mints. So, for example, if you have a date/mint that is typically weakly struck, a high mint state grade can/will still be given to an example which is lacking a full strike. On the other hand, if a certain date and mint is normally very well struck, a weakly struck one can/will be penalized. And like it or not - I don't! - the grading companies are definitely more forgiving when grading especially rare/valuable coins. Doug, they couldn't possibly (and don't) have grading sets like that for most series. The coins simply don't exist for many dates and/or grades that would need to be included. And even if they did, the cost would be beyond prohibitive. Edited to add: What they probably do have is grading sets for major series by type, but certainly not by date and mint. Below is a link from a 2007 article about the PCGS grading set. [URL]http://www.pcgs.com/articles/article_view.chtml?artid=5114&universeid=313[/URL][/QUOTE]
