Here is often one of the most confusing aspects of the coin market. Many different price guides are available to the coin collecting community. Some are online and some are published.
Guides are exactly that. A guide. No price is set in stone, and each will vary depending on the current market cycle.
When searching for a price guide, it is best to use one that is current and up to date. Price guides such as the Red or Blue book are only published once per year. The coin market changes very frequently.
Dealers around the US use the coin dealers newsletter. One issue is issued for raw coins, certified coins, and currency. Published once per week, and also online.

This publication is used by and for dealers. Collectors will not be able to buy and sell coins based on these prices. However, since this is the dealers price guide, you will be able to make wiser purchases knowing what dealers are paying for their material.
Another good price guide is auction prices realized. Most online auction firms and regular auction firms list prices realized from their sales. This allows you to regularly look up what specific coins are bringing in the market place.
Please take into consideration that most prices are based on knowledgeable buyers and sellers.
