Yeah the small sats are best. Even the wheel cards take on ok value when you get something like a
![The Two of Diamonds [2d]](https://pofex.com/images/smilies/2d.gif)
rebuy with 20 seats given away to the 100+9 75k gtd sunday tournament. You just need to have minimum 6 of them to play it right, since it draws a few hundred players. Most players don't rebuy (probably don't have the card to do it). Assuming 700 players with an average rebuy/addon of 1.5 or so per player, the card has a value of roughly $2.
I wouldn't know about the higher value cards - my highest card is a

and I've never seen the opportunity to use it.

Which brings up another point - the weekday GC tourneys are at a horrible time for west coast players, like 1pm or thereabouts.
