How to Find the Value of a Baseball Card
To begin understanding the value of your baseball cards and baseball sets, start with a baseball card price guide. Two of the most popular baseball card price guides are from Beckett and Tuff Stuff Sports Collectors Monthly. You can subscribe to the Beckett site for a low monthly fee and have access to all of their current baseball card listings. Tuff Stuff also has an online version of their baseball card price guide, but a nice benefit to using this guide is that it is free! Something to keep in mind about the different price guides is that they may have different values for the same card! Don’t let that bother you too much; for now you are just using the price guides to give you an idea of the value of your cards …
Baseball cards have value for different reasons to different people. When it comes to the value of a baseball card, it is only worth what someone is willing to pay for it. With this in mind, you should next visit auction sites to see for how much your card is actually selling. Now one interesting thing you will see is that baseball cards often sell on the auction sites for much less than even the low end book value listed in price guides.
Again, keep in mind, from a monetary perspective a baseball card is only worth what someone is willing to pay for it, i.e. why a baseball card may sell for less on an auction site than what the price guide lists. Of course one way to maintain and/or increase the monetary value of your baseball cards is to have them graded.
Keep in mind that the monetary value of a baseball card can be significantly different from its trading value. Where price guides tend to be particularly helpful is in doing trades. This is because collectors tend to rely more on what the price guides says for an equitable trade.
