I went to the mall yesterday to buy a book on mythology, and decided to check out the coin books. While I was checking them out, I noticed a book called "the Blue Book" I opened it up, and it was the same as the redbook whats the difference? stainless
The blue book is a good guide for what dealers might pay for a coin. The red book is a guide for what you should expect to pay.
The key words being "guide" and "might". Every guide, particularly yearly ones as opposed to weekly ones, contains numerous inaccuracies and should not be relied upon too heavily.
