Due to leakage issues for 2012 along with the 2011s (which was more severe), I would estimate about $25-$50 for a set. In the case of Mundy and Fyfe, I'd say about $15 each.
While the 2011 and 2012 prize cards can be sold separately (if it's pre-11, then that drastically reduces the value of the set), they would be much better off in a team set.

In March of 2011 and 2012, before the game actually started, there was a flood of prize cards that was selling on eBay. Not sure of the number, but it was a fair bit. This drastically reduced the value of the 2011s and had some effect on the 2012s (It wasn't as severe as 2011. The only team unaffected was the GWS set for that year. I don't think any of those were released.) By the time efforts were put in to stop them, the damage was already done.
That's why there's such a huge price gap between the 11s and 12s, and the 13s and 14s. Better interal control means less chance of a leak, which means your prizes are worth more.
