A coin dealer could be a single person running the show or it could be a big company. Before selling a coin try to first research on the Internet about the coin value, coin condition, etc, and then contact at least 2-3 coin dealers and discuss the rates.

The first thing you should do while selling your coins, is create a list of the coins and get quotes from different coin dealers. One more source where you can sell your coins is through the Internet. Websites like ebay would come in handy if you would like to sell your coins. You can list the coins in an online auction or set a fixed price and sell. There are many coin sellers and dealers who buy old/rare coins online, so listing your coins online for sale is not a bad idea at all.

If you are thinking of selling your coins through a dealer then make sure the dealer is a reputable and honest person. Find out for how many years the dealer has been in the coin collection business. Always remember, that it does not mean the dealer is an honest and sincere person if he advertises in a leading newspaper. So make sure you ask for testimonials from the dealer.

You can contact the dealer in many ways, through email, phone etc. Make a list of the coin rates the dealer is willing to pay you. The more dealers you contact the better rates you will get. Some dealers collect only a certain type of coin and won't buy other types of coins. So, you can sell some coins to such a dealer and some to other dealers.

Make sure you bargain and get a good quote and once the negotiation is completed sell and get your money immediately.
