Understand the grading system. Because much of a coin's value is based on its grade, it is important to educate yourself on the grading system. A coin's grade corresponds to its condition. The numerical grades run from 0 to 70. A 0 grade coin is a lump of metal barely recognizable as a coin. A 70 grade coin is considered to be in mint condition.
Find collectors' guidebooks. A collector's guide can help you learn more about coin collecting, as well as giving values for specific coins. When using a price guide, look at the most current one you can find, because prices do fluctuate. A library or bookstore will have a selection of coin collecting books. Some useful titles are "Warman's Modern US Coins Field Guide: Values and Identification" by Arlyn G. Sieber, "The Official Blackbook Price Guide to United States Coins" by Thomas E. Hudgeons Jr., and "Coin World Guide to U.S. Coins: Prices &Value Trends" by the "Coin World" editors.
Learn from other collectors. Coin collectors are a passionate bunch and love to discuss all aspects of coins. Network with other collectors to learn coin collecting basics and to find out more about the value of specific pieces. Join a national collectors' society such as The American Numismatic Association. Find fellow collectors in your area through an organization like Meetup, which brings together people who have a shared interest. Attend coin shows to find and network with collectors. Use the coin show calendar at the Web site Festivals and Shows to find events being held near you.
Get an appraisal. If you have a large collection and want to learn its value, or if you need a written valuation of your coins for insurance purposes, contact an expert appraiser. Organizations such as the American Society of Appraisers and the International Society of Appraisers can put you in touch with professionals in your area who specialize in appraising coins.
