I second just_carl's sentiments. Price guides vary significantly for some coins in certain grades. The best guide in my opinion is e-bay's closed auctions (be sure to factor in shipping fees since in some cases a $6 shipping charge will be a significant percent of the overall price paid). Also, for higher-end coins look at Heritage (ha.com) which has over a decade worth of archived auctions and final prices realized. Registration is free and the pictures are great.
