Things You'll Need
Instructions
Create a list of your baseball cards so they won't be handled constantly. Place them in card holders or in a collector's album. Make a note of any cards that seem creased or worn as these will have less value.
Separate the cards by publisher and by year. Bazooka, Donruss, Fleer and Topps are the most popular. Use the magnifying glass to find the copyright date of each card, which is usually in very fine print on the face.
Research the cards online at auction and fan sites to see what price the cards are currently selling for. This will indicate the current value of the cards. Visit baseballcardclassifieds.com to see the current price of baseball cards.
Research the cards at a library. There should be several books available that list collectible cards. The Beckett Sports Cards Value Price Guide should provide sufficient information.
