What brand of marker is recommended for autographs on baseball cards?

Answer 1

The collectable value of a Baseball card is reduced by the signature. The signatures is viewed by card collectors as a flaw in the condition of the card. After it is signed the value will rely on the value of the signature. This is why it is not a good idea to have an expensive card signed. Autographed baseball cards sell at about the price of a signed 8x10 photo or less or about 40 percent the value of a signed baseball (or less) A thin (fine) point Sharpie would be most preferred for the signature. A signature signed with Sharpie would stand out better. If the signature is too thick, on the smaller card, it might make for a sloppy signature, and ruin the display, lowing the price. The color that should be used would be a color that stands out in contrast to the baseball card. in most cases blue would be preferred. Using a ballpoint pen on a baseball card could work, and make for a better "clean signature" but, it could also leave an indent in the card.
