Stephen L. reviewed Photograde: A Photographic Grading Encyclopedia for United States Coins on + 2 more book reviews
A good display of examples of different grades of most US coin types. This should really be used in conjunction with the newer ANA Grading Guide. The user is also advised that many coins suffered from poor strikes in specific periods, such that even a clearly uncirculated coin might appear to have only EF detail - and sometimes less.
