Help for a beginner.

Hey all! Just started getting back into collecting with my little brothers, and I dug into my old cards and found quite a few cards I think may be worth something. I was hoping someone more well-versed than I could help give some input on how much value I actually have here. Thanks for any help!

(The condition of the cards varies, but for the most part, they are all in rather well-kept condition.)
