Didn't you ask that more than once already?
Anyway...
well, hard to say, since they are only tradable p2p.
I would call them collector items, not only due to the fact that they are pretty rare. I bet a lot of them are gone forever in storages of inactive newbies. Beside that, they look quiet nice and offer some unique colors.
These Events where a great fun and a good start into the game for a lot of us.
As far as i know, the Survival one was given in the Zychion Event. These should be extremely rare nowedays. I do only know of one other Ava wich wears it and that might be you, lol.
The red PvP set is from the Bridge of Death Event. There may be a few more around of these, but they are also the most "attractive" ones for different reasons.
In the end, you just need to find the right buyer. Then you could get a nice price for them. If not, you may not even get a decent offer.
