1) Nice cards
2) I have graded a bunch of PC cards with zero intention of flipping them. It comes down to this for me: I like the protection the cases give. You might like having high-grade PC rookies because they are more sought-after, and then in a way they are better additions to your PC, but its all up to you.
Go Cardinals! 12 in 13!
Got a question about Freese rookies? I'm your man.
