If you're not knowledgeable on the value of coins how can you find an honest coin dealer to let you know the real value of your coins?

Do a bit of research on the internet first, then you will have an appx. value of your coins worth, then take them to a dealer and see what he values them at, if the value he gives you is way below what you researched move onto another dealer. Or join a forum. Many people there who can evaluate coins. Check out forum links in this site http://coinfreek.com
