We all want to know the value of the trading cards we have. So, what is the best way to find out? The best methods are through online price guides, monthly magazines or annual books.
Many collectors use a combination of all methods to help determine the value of their collection. For example, online price guides often provide a free or inexpensive method for checking the value of key cards. Monthly magazines offer the added convenience of being able to check prices when you're away from the computer (at a card shop or show). Finally, annual books often provide the most complete listing of cards and prices, especially for oddball cards and sets.
