Where could I find out how much my baseball trading cards are worth?

I wish that we had a collectible card expert on this site. But unfortunately for right now, we don't. These kinds of questions come up fairly frequently here.

When looking for the value of collectible cards, please keep in mind that the condition of the cards makes a huge difference in how much they might be worth. Card collectors get really picky about the conditions of the cards when determining a possible value for them. So, it really would be best if an expert could be viewing the card or cards in person.

Other resources that you might want to try would be a store that sells collectible cards, a bookstore that has books on collectible cards and also books that you will find on the subject in a public library.
