This is the best part of the listing is the part where he says he will not "except" any responsibility for lost mail. For a $35,000 listing? Sure you will.
I'm also of the opinion that price wise, the seller isn't ridiculously out to lunch on his offer. If I took a wild stab at what those cards were worth...and these are just guesses. I've never owned any of these cards, nor have I ever been in the market for any of them.
Some will probably be more than less since I think I've shortchanged a lot of the values. I don't really know what these sell for but below is my best guess:
