It’s not uncommon for a player to have the artist sign a card. This most frequently happens at big events, which typically invite artists to have booths there to sell prints, sell merchandise, and sign cards.
If you’re asking about what that does to the value of the card, that’s a complicated discussion that depends a great deal on the specific card, the artist, and other factors. You would typically have to trade that card in a “heavily played” or “damaged” condition.
