Need some help from the board members?

A friend of mine's brother-in-law has asked me if I wanted these cards. He is hurting for money during this christmas season, but I am unsure if a resale value is worth it to me. The PSA website states that if I want to authenticate the cards its $20 per card. Let me know your thoughts and if there has been any previous sales for either of these cards, what were they? Sorry for the large scans. I havent figured out how to make them smaller. Thanks for the help.
