AFL Trading Cards - Advice

Hey everyone, just after some information/advice on some AFL Trading Cards. The first picture are old coca cola cards. Only 18 in a set and I have about 4 complete sets, not sure they're worth much.

The second is just a bunch of random cards from 2015. I have a heap more, I just pictured the holes and a few random ones.

The third picture are cards that are hand signed by the players themselves. Guessing these would be the most valuable to a WCE fan.
