When trying to determine whether or not a baseball card is autographed, there are a few key things to look for. First, check the back of the card for any sort of certification sticker or stamp. These are usually placed on cards that have been authenticated by a third party. If there is no certification, you can try to look for any signs of smudging or smearing on the front of the card, which could indicate that an autograph has been added. Finally, compare the signature on the card to known examples of that player's signature. If they match up, then it's likely that the card is indeed autographed.
