Cal Ripken baseball card worth can be determined by many different factors. The year the card was produced, the condition of the card, and any special features or autographs on the card can all play a role in determining value. Generally speaking, a Cal Ripken baseball card from the 1980s or early 1990s in mint condition could be worth anywhere from $20 to $100+. However, if the card is autographed or contains special features (such as being a limited edition), then it could be worth much more.
