How would I find prices on basball cards as far as what they arewirth I have many cards

You can go to a bookstore and pick up a copy of a card price guide.

There are also online versions available :

Baseball Card | Value Price Guide | Selling Cards Worth
Free Price Guide for Sports Cards and Collectibles - SportsLizard.com

Good luck. :)

Very true answer above!

There is also this link on our site here https://www.askmehelpdesk.com/collec...ds-125212.html and subsequent links on that link that may be worth having a look at also.

Please also realize, that as far as the value of your cards, the condition of them makes a great deal of difference as to how much they are worth. Baseball card collectors get really picky about the condition of cards. Also, ultimately, your cards will only be worth what someone is going to pay for them. Price guides will give you a general idea as to the possible monetary value, though.
