- The primary source that most coin collectors use to find the value of coins is reference books. While there are many books that list coin values and offer valuable information on coin collecting, the Krause Standard Catalog of World Coins, which is updated each year, is considered the "bible" of coin collecting. The Krause catalog features pictures, metals, weights, and identifying features of coins to help collectors identify and value their coins.
- The Internet is a great resource for coin collectors to both identify and value coins. Sites like Professional Coin Grading Service and Coinlink include identification and price lists, as well as daily updates on the value of certain metals such as gold, silver and copper. Auction sites also provide valuable information for coin collectors when they are unable to find a listed value for a coin. Sites like eBay can give coin collectors an idea of what a particular coin will sell for.
- Coin collectors often find the value of certain coins at coin shows. Dealers and collectors help each other identify and value coins at the shows, and a collector can also get an idea of the value of certain coins by paying attention to what dealers are selling them for. Shows are also a good place for collectors to learn about what coins are popular or being sought after. This is important information because higher demand for a coin increases its value.
- For rare or hard-to-value coins, a collector will pay an appraiser to examine, verify and determine the value of a particular coin. This is usually done only in cases where the collector suspects the coin may be especially rare or valuable.
