Read books which have information about how you can ascertain the value of old coins. You can attend coin exhibitions or fairs and observe how the connoisseurs determine the value of coin. Make sure that the coin has a country of origin mentioned distinctly. It is okay if the mint date is not visible clearly but the wear and tear should not be colossal. You can visit your local coin shop. Mingle with some dealers and discuss about the old coins from a third person point of view. You will soon find a dealer of interest who has inclination to buy your type of coins. Once you have an understanding of the value of the coins, you can make it clear to the dealer that you own those precious coins.
