I'm assuming you are speaking of general US coins. If so, this one is probably one of the better ones... http://www.pcgs.com/prices/
Coin World now has an online version of trends. Many people find these prices to be more accurate than some of the other guides.
:lol: I use the following but understand these are retail pricing not dealer to dealer or wholesale. I deduct 20% and am usually close. www.numismedia.com No need to sign up www.collectit.com Have to sign up and other restrictions may apply
Just remember one thing - all of them are GUIDES. The values are not carved in stone and they can vary greatly for any individual coin.
It could be worth anywhere from $2 to $3000. But I'd wager it's a lot closer to $2. The value of a coin is dependent on many things - year, mint mark and condition of the coin are the primary items. Without knowing these things - value cannot be determined.
I have used this site... http://www.ecoinprices.com/ It is pretty close to what I see in the publications of Coin Prices and Coin Values. Also, Heritage will give you an idea of what their auctions have pulled in for their past closings. And it is FREE.
In my experience there is no online guide or even offline guide that can accurately value coins consistently. Watch the market for awhile. Subscribe to the greysheet, check the COMPLETED auctions on ebay and don't buy anything in haste. Check all the online guides that have been listed here and read every book and magazine article that you can get your hands on. The "feel" for the market will come if you give yourself knowledge. Knowledge is the key to being a successful and happy numismatist. Nick
only real way seems to me is to specialise.No one can possibly know the value of all coins at all times not even close to it. But if you specialise in a small area you have the best chance of knowing
