I use this coin book every day because the detail in it is amazing. If you are interesting in coins it gives you lots of information you can't always find quickly on the internet. Although Krause produce the other century dates this one is the one I use the most.
Having bought the last edition some time ago and found it was the best British Road atlas around I was pleased to buy the new edition. I prefer to use a road map when travelling and use it often to find out where places are. The detail is far better than smaller scale road atlases and now that it is spiral-bound it is even easier to use.
I have found this book to be a valuable and very accurate tool in learning more about old coins. I have all the later publications from Krause that enable me to accurately find and value any coins that may come my way.
