Check out this source. http://www.helium.com/items/462311-assessing-the-value-of-Baseball-cards I can't really tell you exactly which cards are worth alot, but any well known player's rookie card is usually worth something. Also the really really expensive ones are the vintage baseball cards which were sold with tobacco products when baseball was originally developed.
The resale value of baseball cards can be found in Beckett's pricing guide. Beckett is notorius in the sports collectible world and is what most collectors use to determine the value of an item.

They most likely read it
It matters who they are of and how old they are.
Sorry but none of the cards in the set are worth anything and in fact most probably have no book value. Most cards from 1985- present have been mass produce leaving there book value to a min. I you are looking to collect an amazing, valuable collection I would recommend collecting 1975 and earlier when cards were not able to mass produced.

You do. Of course
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.
The most complete baseball card price book would be the 2008 Standard Catalog Of Baseball Cards. You might find it there.
