to CoinTalk pinkcbpoet, and good luck. :thumb:. It depends on how many coins you have, whether they are US, world, or both, and how skilful you are at grading coins according to the 70-point Sheldon scale. If it's just a few coins, post pictures in the What's It Worth Forum. Otherwise: For world coins you should check out your local public library. Most of them have at least the telephone book-sized volumes of the Standard Catalog of World Coins by Krause & Mishler that cover the last few centuries. Again, you can't fully rely on the prices, but you can determine which coins have significant value. Generally modern circulated coins in less than the highest grades are worth the greater of their face value as converted from their own currency to US dollars, or their value as bullion - the trading value of the metal they are made of. . For identification the Guide to United States Coins by Yeoman, usually referred to as the Red Book, is an inexpensive book available at Walmart, Amazon, Barnes & Noble, most hobby shops and all coin shops, among other places. The values are outdated because they change frequently and no printed work can keep up with those changes, but at least they should help you separate the wheat from the chaff, and then concentrate on evaluating the better coins.

Because in many cases the difference in values between heavily circulated coins and high-grade uncirculated ones is measured in the hundreds, or even thousands of times, grading skill is a must for placing accurate values. If you have a lot of high-grade coins, another method of evaluating them is to submit them to a major auction house for an estimate, but there's no way you can get estimates from Heritage, Superior, or any other reputable auction house by next weekend.
