Have 2 briefcases of baseball cards. Need to no value. Can anybody help?

Get the Beckett card guide. I think it's called Beckett's. It's like the Kelly Blue Book of baseball cards. Can probably find it at card shops and comic book shops.

That's right. Beckett is the most used source.

Until you get the book, here's a baseball card checklist/values website:

It's free for 30-days. After that it's cheap: just $3 for 5 months or $6 for one year.

...or scan cards to send them in lieu of payment.

I'm looking at a full set of 1984 topps tiger cards. What is the actual value of these cards?

Yes, Beckett's is the one to go for if you get a book...or check them out here: http://www.mycards.info/
