This book has loads of info. Good info. However, I knocked a star off for these reasons:
1. The coins I looked up, it gave the content weight in English ounces instead of Troy, which is a pain.
2. It didn't seem to care too much about silver coins. There where some in there, but I had three in my safe that this book had never heard of.
3. You need to be a Harvard graduate to find anything in here quickly.
I did, however, still give it four stars because it's excellent for gold coins. It had every gold coin that I could remember that I'd ever bought listed inside with ridiculous amounts of detail.
As the title of this review said, and this is the reason why I took a star off: It's not that great and certainly not worth the cost if you're buying and selling silver coins. They advertize it as being the "end all reference." If they'd said specifically it was that about gold coins I'd agree.
Also, I'd advise to any noob who's buying this book to make money with: DO NOT show it to your customers when you're looking at their stuff. I'm not telling you to be dishonest, I'm telling you this because you will never buy a coin off of anyone who sees their stuff in this book. Just like with any "value" guide, it'll tell you that some coin that isn't worth squat (other than it's content) is worth $1000. WHERE!?!?!? THE MOON? I have, in fifteen years, never been able to sell a foreign coin for anything other than melt price. I've looked, I've called people and I've tried the various places on the internet. THEY AREN'T WORTH ANYTHING. Unless you have a bunch, they're current, and you know where to exchange them at a not so horrible rate. Look up someone's shilling in this book and they will be buried with it.
