The value of a coin can be found in a number of different ways. For commonly known coins, there are usually guides and charts available online. If the coin is rare, one can ask a specialist, coin traders or coin collectors.
Any coin website can give valuations on coins, but they will only be an average or best guess on current market trends.
If you need a valuation, take your coins to a reputable coin dealer who will be able to make a valuation based on an examination of the condition and authenticity of your coins.
There are many, many sites that post values of U.S. coins. As one such example I've found that www.numismedia.com has reasonable valuations for most coins.
One can find websites for coin collector online. Such as coinflation website, coppercoin website, coinnetwork website, smalldollars website, coinlink website, and traildies website.
