Tony, to answer your question, as far as value, #4 and #5 may be any number of different cards. I'd feel pretty comfortable saying that #3 belongs to the Kelly (mascot) card as it generally fetches over $1000 in any condition. It is pretty difficult to obtain as well.
There are certain players and teams that just don't come up for sale at all. There are players in Series 8 in particular that are super tough. A bidding war for an obscure player can push a card into the 4 digit range. The players who have had MLB experience and who are readily known also draw a premium.
I'm surprised no one has shared the Jones, Oklahoma for the viewers at home. It's a wonderful set and it's been great working on aspects of it with the fellas who have posted in this thread.
I'm particularly fond of this pose of Eugene DeMontreville. I picture him having tried to leg out a throw to first base, all the while his cap comes off, and he's thrown out by a half step. The miffed look on his face confirms it.

Already shared by David, but the relaxed pose is just killer:
